CROSS-REFERENCE OF RELATED APPLICATIONS

This application is the U.S. National Phase under 35 U.S.C. § 371 of International Patent Application No. PCT/JP2019/020198, filed on May 22, 2019, which in turn claims the benefit of Japanese Application No. 2018-106209, filed on Jun. 1, 2018, the entire disclosures of which Applications are incorporated by reference herein.

TECHNICAL FIELD

The present disclosure generally relates to input devices, and specifically, to an input device used for input to various electronic apparatuses.

BACKGROUND ART

Patent Literature 1 discloses a touch panel (an input device) including a plurality of pressure sensing elements (pressure detectors). Each pressure sensing element includes: a substrate; a conductive structure member (a pressing member) extending from the substrate; an elastic electrode part (elastic body) facing a tip end of the conductive structure member; and an electrode support member facing the substrate via the conductive structure member and the elastic electrode part, supporting the elastic electrode part, and being flexible. In the pressure sensing element, as pressing force that presses the electrode support member to the substrate increases, a contact area between the conductive structure member of a conductive structure and the elastic electrode part increases. This increases a resistance value between the elastic electrode part and a conductor layer of the conductive structure. Based on a change in the resistance value, a change in the pressing force, which acts on the pressure sensing element is detectable.

In Patent Literature 1, when the contact area between the conductive structure member of the conductive structure and the elastic electrode part increases, the conductive structure may locally apply pressing force to the elastic electrode part. This may cause plastic deformation and/or deterioration of electrical characteristics of the elastic electrode part, which may cause deterioration of the performance of the input device.

SUMMARY OF INVENTION

An object is to provide an input device with reduced deterioration of performance.

An input device of one aspect of the present disclosure includes one or more pressure detectors. Each of the one or more pressure detectors includes an electrode, an elastic body on the electrode, a pressing member on an opposite side of the elastic body from the electrode, and a protection member between the elastic body and the pressing member. The protection member has higher strength than the pressing member.
