Abstract
An induction-heating cooking device includes a light-transmissive cooking board on which a cooking container to be heated is to be placed; a heating coil for heating the cooking container; light emission means for emitting a light beam; and light-transmissive light conducting means for allowing the light beam emitted by the light emission means to be propagated therethrough. The light beam lights up an outer peripheral portion of the light conducting means.
