Title:
INPUT TERMINAL
Document Type and Number:
WIPO Patent Application WO/2016/002460
Kind Code:
A1
Abstract:
A panel (21A) of an input terminal (1) is provided with a base substrate (501) having a first principal surface and a second principal surface that oppose each other; a piezoelectric film comprising a uniaxially stretched polylactic acid and having a third principal surface and a fourth principal surface that oppose each other; and rigid bodies (601, 601R) that are placed at the ends of the first and second principal surfaces of the base substrate (501) and that, by opposing each other with the base substrate (501) interposed therebetween, partially prevent torsional deformation of the base substrate (501). Displacement-detection electrodes (201, 202, 203, 204) are formed on the first principal surface of the piezoelectric film (101) so as to divide the first principal surface into quarters. Displacement-detection electrodes (201R, 202R, 203R, 204R) are formed on the second principal surface of the piezoelectric film (101) so as to oppose the displacement-detection electrodes (201, 202, 203, 204) of the first principal surface.
