  As shown in FIG. 6, when the case lid 1b is slid in the direction of the arrow X by the operation with the thumb, the electric heating unit 2 is exposed to the outside from the open surface of the case body 1a. However, by simply sliding the case lid 1b, power cannot be supplied from the battery unit 3 to the heating heater 2a, and the heating unit 2 does not generate heat.

  When the case lid 1b is slid by the operation with the thumb to expose the electric heating part 2 from the open surface of the case body 1a, and the plate surface of the case lid 1b is slightly bent and deformed by the pressure P with the thumb as shown in FIG. The switch portions 4a and 4b are pressed by the projecting pieces 12a and 12b of the case lid 1b so that power can be supplied from the battery portion 3 to the heater 2a. Thereby, while being able to perform ignition operation easily, since a young person cannot understand the operation method easily, a favorable CR function can be provided.

  At the sliding position of the case lid 1b, the projecting pieces 12a and 12b provided on the inner surface of the case lid 1b and the switch portions 4a and 4b are positioned relative to each other, and the thumb is positioned at the button portion of the switch portions 4a and 4b. Thus, if the case lid 1b is pressed a little with the thumb, the projecting pieces 12a and 12b come into contact with the switch parts 4a and 4b, the switch parts 4a and 4b are operated, and the battery part 3 can supply power to the heat generating heater 2a. After ignition, if the thumb is removed from the case lid 1b, the case lid 1b is returned to its original position by the tension spring 7 so as to close the electric heating portion 2.

  In this battery-type lighter, a light-emitting element 25 (see FIG. 1) such as a light-emitting diode is mounted on the same surface of the circuit board 5 having the switch portions 4a and 4b, and an ignition control IC (not shown) or the like is circuitized. By surface mounting on the opposite surface of the substrate 5, the light emitting element 25 can be connected to the circuit so that it is turned on while the heater 2a is in operation and blinks when the heater 2a is stopped. With the light emitting element 25, the operation of the heat generating heater 2a can be reliably recognized, and the circuit can be connected so that the battery unit 3 is turned on during charging, is turned off after charging, and blinks when the storage capacity is reduced.

  The electric heating unit 2 is a circuit that can stop power supply within a few seconds after the operation of the heater 2a if a capacitor (not shown) having a predetermined capacity is provided on the same side of the circuit board 5 on which the IC for ignition control is mounted. It can also be configured. As a result, it is possible to prevent energization for more than the time required to ignite an ignited object such as a cigarette, thus preventing wasteful consumption of electric power and taking safety measures.

  Although the above-described embodiment has been described mainly based on the case where a fire is applied to an ignited object such as a cigarette, it is also possible to target an ignited object such as an incense stick or a candle.
