<P>PROBLEM TO BE SOLVED: To provide an induction heating cooker in which a light-emitting source for illuminating input keys of an operation part is arranged on the same board with other components. <P>SOLUTION: An induction heating cooker comprises: a heating part heating a heating object placed on a top plate 2; an operation part arranged on the top plate 2 and including input keys for an input of a heat condition of the heating part; and a display part arranged on the top plate 2 and displaying contents of the input through the operation part. The operation part includes: printing 31 representing the input keys; a touch switch board 33 having capacitance change detection part 34 arranged at a location corresponding to a location of the printing 31 for detecting a capacitance change; a light-emitting element 21 located near the capacitance change detection part 34 of the touch switch board 33 and emitting light in its side face direction; a light guide body 22 provided on a top face of the capacitance change detection part 34 for bending an optical axis of light from the light-emitting element 21 at an approximately 90-degree angle to illuminate a surface printed with the printing 31; and spacers 23 for providing the light-emitting element 21 and the light guide body 22 between the top plate 2 and the touch switch board 33. <P>COPYRIGHT: (C)2013,JPO&INPIT |
