SPIRAL TUBE-LIKE HEATER

摘要

Provided is a spiral tube-like heater capable of accurately controlling a temperature over a wide range and reducing a problem in safety caused by the disconnection of a heating element. In a spiral tube-like heater (1) in which a first heat-resistive resin tape (4) and a second heat-resistive resin tape (6) are laminated through an adhesive layer (10) while two or more heating elements (2) extending in the longitudinal direction are interposed therebetween, the two or more heating elements (2) are disposed while being insulated from each other and are respectively and independently joined to different lead wires (8) from the outside.
