To suppress wasteful electric power consumption and effectively warm a user with a flat warmer such as an electric carpet.
This flat warmer is equipped with a main body 6 comprising a heating body 2, a temperature detecting body 3 disposed close to the heating body 2, a heat conductive sheet 4, and a base material 5 provided between the heating body 2/the temperature detecting body 3 and the heat conductive sheet 4 and excelling in compression deformablity, and a temperature control part 7 for controlling a current passed through the main body 6, and is adapted to operate such that the amount of heat generated by the heating body 2 is increased when a user stays on an upper surface of the main body 6 and that the amount of heat generated by the heating body 2 is decreased when the user moves off from the main body.
