<p><P>PROBLEM TO BE SOLVED: To prevent a touch switch from being hidden by a heating object mounted on a top plate. <P>SOLUTION: A conductive thin film made of a metal material is formed on an underside of a top plate 7. A touch operation part 35 for adjusting an output of an induction heating coil is fitted at right and left end parts of the top plate 7. The touch operation part 35 is equipped with a capacitance type touch switch 37 of having a touch detection electrode 40 structuring from a part of the conductive thin film. The touch detection electrode 40 is connected to a touch detection circuit through a connection pattern 44 film-formed on the underside of the top plate 7, and a conductive electrode 43. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
