Abstract

Provided is a cylindrical heater which is easy to install and which has high heating efficiency. The cylindrical heater is characterized by being provided with: a cylindrical elastic body part 200; and a flexible printed wiring board 100 that is provided integrally with the elastic body part 200 and that has formed therein a heating circuit, wherein a heating part 110 that has formed therein the heating circuit in the flexible printed wiring board 100, is provided to the elastic body part 200 so as to be positioned along the inner circumferential surface of the elastic body part 200, with both ends thereof being apart from each other with a spacing S therebetween in the circumferential direction, and so as to be exposed on the inner circumferential surface side.

Description

technical field [0001] The present invention relates to a cartridge heater having a flexible printed wiring board on which a heating circuit is formed. Background technique [0002] Conventionally, in order to heat a cylindrical member or a columnar member, a cylindrical heater provided so as to cover the outer peripheral surface of these members is known. refer to Figure 6 , the cartridge heater in the conventional example will be described. Figure 6 is a schematic sectional view of a conventional cartridge heater. [0003] The illustrated cartridge heater 700 includes a double-sided tape 710 , a flexible printed wiring board 720 attached to the double-sided tape 710 , and a holding member 730 for holding the flexible printed wiring board 720 . A heating circuit is formed on the flexible printed wiring board 720 and has a function of generating heat by applying a voltage. In addition, the holding member 730 is formed of a cylindrical member. [0004] The procedure for ...
