Claim 0:
1. A pressure detection element of a capacitive system, the pressure detection element comprising:
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,
wherein 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, and
wherein a protrusion is provided at the apex at the center of the end surface of the pressing member.
