To inhibit a junction between an electrode terminal and a power receiving electrode from being damaged while suppressing an increase in the amount of heat transfer from a holding body to a support.SOLUTION: A heater includes: a holding body having a substantially planar first surface substantially orthogonal to a first direction and a second surface on the side opposite to the first surface; a tubular support; a resistance heating element arranged inside the holding body; a power receiving electrode electrically connected to the resistance heating element; an electrode terminal joined to a power receiving electrode through a metal brazing material; and an insulating tube in which a through hole housing the electrode terminal therein is formed. On the second surface of the holding body, a stepped part is formed, engaged with the tip on the side opposite to the holding body in the insulating tube in the second direction orthogonal to the first direction.SELECTED DRAWING: Figure 7 【課題】保持体から支持体への熱移動量の増大を抑制しつつ、電極端子と受電電極との接合部が損傷することを抑制する。【解決手段】加熱装置は、第１の方向に略直交する略平面状の第１の表面と、第１の表面とは反対側の第２の表面とを有する保持体と、管状の支持体と、保持体の内部に配置された抵抗発熱体と、抵抗発熱体に電気的に接続された受電電極と、金属ろう材を介して受電電極に接合された電極端子と、電極端子を収容する貫通孔が形成された絶縁管とを備える。保持体の第２の表面には、第１の方向に直交する第２の方向において、絶縁管における保持体に対向する側の先端部と係合している段差部が形成されている。【選択図】図７
