<p>A touch switch is composed of an EL light emi L Ling layer (1) configured by stacking a fluorescent layer (1b) and an insulation layer (1c) between first electrodes (1a) and a second electrode (1d), a judgment means (10) for making a judgment on touch manipulation with the first electrode (1a) by an operator and an EL driving unit (11) for driving the EL light emitting layer (1) for light emitting, with each of a plurality of first electrodes (1a), each of plurality of fluorescent layers (1b) and each of plurality of insulation layers (1c) being provided as a set and the second electrode (1d) being provided as a single electrode with respect to the plurality of first electrodes (1a), wherein the judgment means (10) makes a judgment on which of the plurality of first electrodes (1a) has been touched by an operator on the basis of a high-frequency component inputted from the second electrode (1d) through the first electrode (1a) each time the touch switch is touched by an operator.</p>
