経済的である。[Operation] The present invention is constructed as described above, but in short, an electrically conductive sheet material A and one or more layers of an electrically semiconductive sheet material B are formed with a gap parallel to the gas flow direction. By applying a voltage between two adjacent electrically conductive sheet materials A-A to form a potential difference, the electricity is transferred to the space between the electrically conductive sheet materials. It is possible to form an electric field through the semiconductive sheet material B. With such a configuration, in terms of strong electrical engineering, the electrically semiconductive sheet material B acts as an insulating layer, and the electrically conductive sheet material A acts as a conductive layer (or electrode), and the electrically conductive sheet material A voltage can be applied between the materials A and A, and an electric field can be created between them through the electrically semiconductive sheet material B, and in terms of electrostatic engineering, the electrically semiconductive sheet material B acts as a conductor, so the surface of the electrically semiconductive sheet material B acts as a conductor. There is no accumulation of charge that distorts the electric field between the electrically conductive sheet materials A-A. In addition, it is possible to uniformly conduct electricity and heat between electrical resistors located over a short distance, and it is safe and economical because it can be used at a lower voltage than the conventional method in which electricity is applied from both ends of the ceramic.

This is because if the resistivity value is less than 1 x 105, the electrical resistance is too low and when voltage is applied, too much current will flow, generating heat and increasing power consumption.
This is because if it exceeds m, the electrical resistance will be too high and charges will accumulate on its surface.

ある。The electrically conductive sheet material A used in the strength tree invention can also be used by changing the composition of the electrically semiconductive sheet material B, but other materials such as metal foil, conductive paper, or ceramic sheets mixed with metal, graphite, etc. can also be used. etc. can be used. In addition, the specific resistance value of the electrically conductive sheet material A depends on the purpose of use of the honeycomb-like laminate.
It is set appropriately in relation to the specific resistance value of the electrically semiconductive sheet material B, but it needs to be at least 1/10 or less of the specific resistance value of the electrically semiconductive sheet material B. This is because when the ratio exceeds 1/10, the electrical difference between the electrically conductive sheet material A and the electrically semiconductive sheet material B decreases, and the electrically semiconductive sheet material B is used as an insulating layer, and the electrically conductive sheet material A is used as an insulating layer. This is because the purpose of the present invention of using the conductive layer as a conductive layer cannot be achieved. A preferable range of the specific resistance value of the electrically conductive sheet material A is 17,100 or less of the specific resistance value of the electrically semiconductive sheet material B, and within this range, the above purpose can be most clearly achieved.
