PROBLEM TO BE SOLVED: To provide a handle heater device which detects contact to a subject even when a handle heater is in a current-carrying condition.SOLUTION: The handle heater device includes: a handle heater 103 mounted on a steering handle and composed of an electric resistant body generating heat by electric energy; an inductor Lb connected to one terminal of the handle heater 103 in series; and at least one switch 101 and/or 102 turning on or off power supply to the handle heater 103. A sensor circuit 106 determining the presence or absence of contact between the steering handle and the subject on the basis of the size of capacitance of the handle heater 103, is electrically connected to the one terminal. At least one switch corresponds to at least one of the switch 101 connected to the one terminal of the handle heater 103 via the inductor Lb in series, and the switch 102 connected to the other terminal of the handle heater 103 in series.

    【課題】ハンドルヒータが通電状態であっても被検出体の接触を検知するハンドルヒータ装置を提供する。【解決手段】操舵ハンドルに備えられ、電気エネルギにより発熱する電気抵抗体で構成されたハンドルヒータ103と、ハンドルヒータ103の一方の端子に直列に接続されたインダクタLbと、ハンドルヒータ103への電力供給をオンまたはオフする少なくとも1つのスイッチ101および/または102とを備え、一方の端子には、ハンドルヒータ103の静電容量の大きさに基づいて操舵ハンドルと被検出体との接触の有無を判定するセンサ回路106が電気的に接続され、少なくとも1つのスイッチは、ハンドルヒータ103の一方の端子にインダクタLbを介して直列接続されたスイッチ101、および、ハンドルヒータ103の他方の端子に直列接続されたスイッチ102の少なくとも1つである。【選択図】図7C
