1. A heater device for heating a user's body seated on a seat, comprising:
a heat generating portion that is arranged in a recess recessed from a surface of the seat and generates heat when energized, heating a portion of the user's body that is not in contact with the seat;
a distance detection unit that detects a distance between the portion of the user's body around the heat generating portion and the heat generating portion; and
a control unit that controls energization of the heat generating portion, wherein
the control unit includes
a first control portion that controls an energization amount of the heat generating portion so that an output of the heat generating portion becomes equal to or higher than a predetermined output, when the distance detected by the distance detection unit is longer than an offset distance between the heat generating portion and the surface of the seat, and
a second control portion that controls the energization amount of the heat generating portion so that the output of the heat generating portion becomes less than the predetermined output, when the distance detected by the distance detection unit is equal to or less than the offset distance.
