ABSTRACT:
A touch switch is composed of an EL light emitting layer configured by stacking a fluorescent layer and an insulation layer between first electrodes and a second electrode, a judgment unit for making a judgment on touch manipulation with the first electrode by an operator and an EL driving unit for driving the EL light emitting layer for light emitting, with each of a plurality of first electrodes, each of plurality of fluorescent layers and each of plurality of insulation layers being provided as a set and the second electrode being provided as a single electrode with respect to the plurality of first electrodes, wherein the judgment unit makes a judgment on which of the plurality of first electrodes has been touched by an operator on the basis of a high-frequency component inputted from the second electrode through the first electrode each time the touch switch is touched by an operator.
