PROBLEM TO BE SOLVED: To provide an electrostatic capacity type touch sensor with a simple configuration which utilizes capacitive coupling between a touch electrode and a finger of a person.SOLUTION: A touch sensor element 1 includes: a touch electrode 2 that generates capacity between the ground and the same; and a touch detector 10 the input end of which is connected to the touch electrode 2. The touch detector 10 has an amplifier 11 which includes an input terminal connected to the input end of the touch detector 10 and the output terminal connected to the output end of the touch detector 10. An equalization switch SW1 performs ON/OFF operation to switch electrical connect/non-connect between the input terminal and the output terminal of the amplifier 11. |
