Abstract
A heater device includes a heater surface facing one side in a predetermined direction. The heater device includes a transmission electrode and a reception electrode arranged on the other side in the predetermined direction with respect to the heater surface, and an insulation coating layer that covers the transmission electrode and the reception electrode on the one side in the predetermined direction. The transmission electrode and the reception electrode are electrically connected to a contact detection unit, to detect contact or proximity of an object to the heater surface by a change in a capacitance therebetween. The insulation coating layer has a first component part made of an insulating member, and a second component part having a smaller relative permittivity than that of the first component part. The second component part is located between at least one of the transmission electrode or the reception electrode and the heater surface.
