Abstract

A small and thin pressing direction sensor that can continually detect pressing directions in the angle range of 360 degrees is provided. This pressing direction sensor includes a ring-like resistive film pattern, a first electrode pattern, and a conductive member that electrically connects the resistive film pattern and the first electrode pattern when pressed. The voltage of the first electrode pattern represents the pressing direction. This pressing direction sensor may further include a second electrode pattern. A signal representing the pressing force can be obtained from the second electrode pattern when the pressed conductive member is brought into contact with the second electrode pattern.
