Abstract
A touch control apparatus for an electric appliance has a plurality of conductive electrodes formed on a glass plate by heating a layer formed of a mixture of conductive powder and glass powder on a surface of the glass plate, the glass plate being used as a glass plate of an operation input section of the electric appliance. The heating produces an integral bonding of the layer and glass plate so that the control apparatus has a high mechanical strength and a long life and provides an electric appliance with a water-tight structure.
