摘要:
With use of a variable-capacitance capacitor, a position indicator in which both the initial rise characteristic at the time of writing pressure detection and the resolution of the writing pressure are improved and that is suitable to be used for a portable terminal is realized. The variable-capacitance capacitor includes a dielectric (71) having a first surface part (71a) and a second surface part (71b) that are opposed. A conductor member (71 c) is disposed on the first surface part (71 a) of the dielectric (71), and it functions as a first electrode part. A conductor member (71d) is disposed on the second surface part (71b) of the dielectric (71). An electrically-conductive member (74) to which an elastic member (75) that functions as a terminal part is connected is disposed opposed to the conductor member (71d) and the electrically-conductive member (74) gets contact with the conductor member (71d), which forms a second electrode.
