To provide a heating toilet seat device capable of improving safety.
The heating toilet seat device includes: a resonance circuit having an induction heating coil, and a resonance capacitor; a conductive body which is induction-heated in a magnetic field generated by the induction heating coil; a toilet seat provided with the induction body; an invertor which has a first switching element, and controls the power supplied to the resonance circuit; a rectification part for rectifying a current supplied from commercial power; a pressure lowering part which has a second switching element, lowers a rectification output of the rectification part to supply to the invertor; a switch which is mechanically operated by use of the toilet seat by a user; and a control part which performs induction heating of the toilet seat by lowering the rectification output by controlling the switch of the second switching element, and supplying to the invertor. The pressure lowering part lowers the rectification output to the predetermined value or less regardless of an instruction from the control part, and supplies to the invertor.
