Abstract
An electrostatic capacitive touch sensor including a substrate having a group of fixed electrodes formed thereon; and a movable electrode plate that is integrally molded by using rubber or resin having an elastic property as a whole and that has at least a face which opposes the group of fixed electrodes and is made of a conductive rubber or a conductive resin. The group of fixed electrodes and the movable electrode plate form a plurality of variable electrostatic capacitive sections, and in response to the magnitude and the direction of a force applied onto the movable electrode plate, the electrostatic capacitances of the respective variable electrostatic capacitive sections are allowed to change.
