HEATER APPARATUS

A heater apparatus according to the present invention is provided with: a heat generating unit (12); an outer surface (14a); a detection unit (13) that detects if an object (5a) has touched the outersurface; a first control unit (S210, S220) that stops the supply of electricity to the heat generating unit or reduces the amount of electricity supplied thereto when the object touches the outer surface in a first region (14c) where the outer surface overlaps the detection unit in a first direction (Z) connecting the heat generating unit and the outer surface; a temperature sensor (15) that is disposed so as to be offset from the detection unit in a second direction (X) intersecting the first direction and detects the temperature of the heat generating unit; a second control unit (S100, S110,S120, S130, S101, S121) that controls the temperature of the heat generating unit on the basis of the temperature detected by the temperature sensor; and a third control unit (S200, S220, S230, S221)that reduces the amount of
