Abstract: A heat generator includes an electrode terminal, a heating element, an electrically conductive housing, and an insulator. The electrode terminal is stacked on the heating element in a stacking direction. The housing houses a stacked body formed of the heating element and the electrode terminal. The stacked body includes a pair of side wall surfaces each extending in the stacking direction, an element side end surface, and a terminal side end surface. The element side end surface is in close contact with the case inner wall surface. Both the terminal side end surface and the pair of side wall surfaces are entirely in close contact with the case inner wall through the insulator. The housing includes a pair of facing walls facing and extending along the pair of side wall surfaces to serve as a positioning member that restricts the heating element from moving in the intersecting direction.
