On the other hand, a sound data determined to be unusable in the management information is invalidated so that it cannot be used.

Electronic device, data usage method, and recording medium

A touch sensor in which an increase in manufacturing processes is suppressed and which can be provided inexpensively is obtained. A touch sensor () has a structure in which resistance membranes (A,B) and membranes (A,B) made of pressure sensitive ink are formed on predetermined places of a film (), two parts (A,B) on which the resistance membranes (A,B) are formed are interfolded so that the resistance membranes (A,B) face each other, two parts (C,D) on which the membranes (A,B) are formed are interfolded so that the membranes (A,B) face each other, and the interfolded two parts are further interfolded.
