Abstract
An induction heating device includes a top plate, a thermo-sensitive device, a temperature detector, a coil, a controller, and a light-emitting section. The top plate places thereon a cooking utensil containing material to be cooked. The thermo-sensitive device changes its electrical characteristics with the temperature of the cooking utensil. The temperature detector detects the temperature of the cooking utensil based on the electrical characteristics of the thermo-sensitive device. The coil heats the cooking utensil. The controller controls the coil based on the temperature information of the temperature detector, thereby controlling an amount of the electric heating power to be supplied to the cooking utensil. The light-emitting section emits visible light to the area over the thermo-sensitive device. The light from the light-emitting section illuminates the area over the thermo-sensitive device through the top plate.
