PROBLEM TO BE SOLVED: To provide a heater element capable of suppressing temperature unevenness during actuation, and stably raising temperature of an outer surface of an installation body.SOLUTION: Provided is a heater element 15 wound around an approximately bar-shaped installation body 3 and raising temperature of a surface of the installation body 3 during actuation. The heater element 15 comprises: a base material 16 formed of a flexible sheet body; and a linear heater 27 to be supported by the base material 16. The heater element is wound along a peripheral direction of the installation body 3 in a state that end edges of the base material 16 abut mutually, and then is disposed so as to cover the outer surface of the installation body 3. The linear heater 27 has a temperature reduction suppression part 32 which is bent and disposed so that it can suppress reduction in temperature of a region of the abut part, which is formed by abutting the vicinities of the end edges of the base material 16 when the heater element is wound around the installation body 3.
【課題】作動時に温度ムラが生じるのを抑制して、取付体の外表面を安定して昇温可能なヒータエレメントを提供すること。【解決手段】略棒状の取付体3の周囲に巻き付けられて、作動時に、取付体3の表面を昇温可能なヒータエレメント15であり、可撓性を有したシート体からなる基材16と、基材16に支持される線状ヒータ27と、を有し、基材16の端縁相互を突き合わせるようにして、取付体3の周方向に沿って巻き付けられて、取付体3の外表面を覆うように配置される。線状ヒータ27が、取付体3への巻き付け時に、基材16の端縁近傍を突き合わせて構成される突き合わせ部の領域の温度低下を抑制可能に曲げて配置させた温度低下抑制部32、を設けて構成される。【選択図】図9
