Patent ID: 7217900

Claim:
A cooking stove comprising: a glass top plate covering a top surface of a cooking stove main body accommodating heating means; an operation circuit board having an electrode pattern formed to detect an electrostatic object and mounted on a back surface of the glass top plate; electrical capacitance detecting means for detecting an electrostatic object located on the part of a front surface of the glass top plate which is opposite to the electrode pattern, the electrical capacitance detecting means being constructed using the electrode pattern; a nonconductive bonding layer bonding the back surface of the glass top plate tightly to a part of the operation circuit board on which the electrode pattern is formed; a display mark provided on the part of the front surface of the glass top plate through which light is transmitted; a switch mark provided on the front surface of the glass top plate and having a first positional relationship with the display mark; and a case having a display opening and an operation circuit board opening respectively corresponding to the display mark and the switch mark with the first positional relationship, the case being mounted on the back surface of the glass top plate so that the display opening is positioned at the display mark, wherein the part of the operation circuit board on which the electrode pattern is formed is bonded by the bonding layer to the back surface of the glass top plate via the operation circuit board opening.
