摘要:
Surface acoustic waves are excited in two diagonal directions from each of IDTs (excitation elements) disposed on the upper side and the lower side of a non-piezoelectric substrate, and the surface acoustic waves propagated on a detection region are received by IDTs (receiving elements) disposed on the left side and right side of the non-piezoelectric substrate so that a position of an object touching the non-piezoelectric substrate is detected based on the reception results. In each IDT, comb-like electrode fingers are joined to two facing electrode bases (signal electrode and ground electrode) in such a manner that the comb-like electrode fingers are inclined from a facing direction of the electrode bases.

A surface acoustic waves is excited from an excitation element disposed on a substrate, the surface acoustic wave propagated on the substrate is received by a receiving element positioned on the substrate so as to face the excitation element, and the position of an object touching the substrate is detected based on the reception result. The wave number of a burst wave applied to excite the excitation element is made equal to the number of the comb-like electrode fingers of an IDT of the excitation element.
