Title:
TOUCH PANEL
Document Type and Number:
WIPO Patent Application WO/2016/002459
Kind Code:
A1
Abstract:
A touch panel provided with a first main surface and a second main surface that oppose each other. The first main surface is an operation surface. The touch panel is also provided with a panel member (21) where a deformation is caused by a pressing force on the operation surface; a main functional part (20) comprising a flat membrane–type piezoelectric film (200), which is provided with a mutually-opposed third main surface and fourth main surface, on both of which surfaces are arranged piezoelectric voltage–detecting electrodes that detect the piezoelectric voltage corresponding to the amount of deformation in the piezoelectric film (200); and an adhesive layer (22) that is formed between the second main surface of the panel member (21) and the third main surface of the piezoelectric film (200) and bonds together the panel member (21) and the main functional part (20), causing the second main surface of the panel member (21) to oppose the third main surface of the piezoelectric film (200). The surface of the adhesive layer (22) that faces the third main surface of the piezoelectric film (200) is divided into multiple regions and has at least 1 combination of 2 regions in which the elastic moduli differ.
