Document Type and Number:
Japanese Patent JP7234233
Kind Code:
B2
Abstract:
A pressure detection element of a capacitive system includes a dielectric having two opposing surfaces including a first surface and a second surface, a conductor layer provided on the first surface of the dielectric, a conductive elastic member provided on the second surface of the dielectric, a spacer that positions the conductive elastic member at a predetermined distance from the second surface of the dielectric, and a pressing member configured to push the conductive elastic member toward the dielectric. An end surface of the pressing member that presses the conductive elastic member has a predetermined curvature, with an apex at a center of the end surface. A protrusion is provided at the apex at the center of the end surface of the pressing member.
