Abstract
A cooking device, that prevents erroneous operations which are not intended by a user, includes a top plate on an upper surface of a main body, a heating section to perform induction-heating of a bottom surface of an object to be heated that is placed on the upper portion of the main body, a control unit to control heating output of a heating coil, one or more operation switches at the top plate, a light source to illuminate the operation switch, and a connection terminal to electrically connect the operation switch to the control unit. The operation switch includes a conductive detection section to detect that a user touches the conductive detection section based on capacitance change, and a conductive connection section contacted with the connection terminal. The connection section is formed to be directly connected to a portion of an outer edge of the detection section.
