PROBLEM TO BE SOLVED: To provide a touch sensor for a handle of a pachinko machine which highly resists static electricity by preventing the breakage of the touch sensor otherwise caused by errors in wiring and connection and the like against super high voltage static discharges peculiar to pachinko game machines. SOLUTION: The touch sensor comprises an oscillation circuit 10 having an oscillation coil L and an electrode 15 connected to the oscillation circuit 10 through a resistor R1 and detects a human body depending on changes in the oscillation conditions of the oscillation circuit 10 as caused by approach of the human body to the electrode 15 or contact of the human body with it. It is provided with the first gap G1 for static discharge between the connection point of the electrode 15 and the resistor R1 and a frame ground FG and the second gap G2 for static discharge between the frame ground FG and the power source GND.
