Abstract
PURPOSE:To achieve a thickness accuracy, by applying a grinding and the formation of an electrode on a pyroelectric thin sheet fixed securely into a through hole with a step on a substrate to reduce the generation of a cracking in the sheet. CONSTITUTION:A step 3 is formed on a substrate 1 at a position of a specified depth in a through hole 2 piercing it 2. A pyroelectric sheet 4 with a proper thickness is fitted into the through hole 2 partially projected from the top 1a of the substrate. Then, a portion projected upward from the top 1a thereof of the pyroelectric sheet 4 is subjected to a grinding to be flush with the top 1a thereof. Then, electrode films 5 and 6 are formed on the top and bottom surfaces of the pyroelectric sheet 4 by evaporation or the like from the top and bottom surfaces of the substrate 1 and the formation of an electrode and a polarization treatment are performed. Then, the substrate 1 is cut into a specified shape according to a cutting line 7 and cut pieces are fixed separately in an infrared detector to use.
