To provide an induction-heating type heating toilet seat device with high safety.
The heating toilet seat device includes: a resonance circuit 540 having an induction heating coil 222, and a resonance capacitor 541; a conductive body 231 induction-heated in a magnetic field generated by the induction heating coil 222; a toilet seat 200 provided with the induction body 231; an invertor 550 which has a first switching element 551, and controls the power supplied to the resonance circuit 540; a rectification part 510 for rectifying a current of a power supply; a pressure lowering part 520 which has a second switching element 521, lowers a rectification output, and supplies to the invertor; a first power device 420 for driving the body control part which controls switching of the second switching element 521, switches the pressure lowering amount of the rectification output, supplies to the invertor, and induction-heats the toilet seat 200; and a second power device 515 for lowering pressure. Power distribution of the resonance circuit 540 can be stopped regardless of the instruction of the body control part 410 by stopping the drive voltage supplied to the pressure lowering part from the second power device 515.
