PROBLEM TO BE SOLVED: To provide a seating sensor which is excellent in resistance to static electricity.SOLUTION: A seating sensor comprises: a circuit part CI1; and a ground wire 60 which is arranged between a pair of insulation sheets 10s and 20s, and connected to a ground side with respect to the circuit part CI1. The circuit part CI1 comprises: a switch part SWB1 having at least one of pressure sensitive switches SW1 and SW2 which are arranged on the pair of insulation sheets 10s and 20s, and have a pair of electrodes facing each other across an opening 31 formed on a spacer 30 arranged between the pair of insulation sheets; and a resistance element R1 which is arranged between the pair of insulation sheets 10s and 20s, and electrically connected parallel to the switch part SWB1. The ground wire 60 surrounds the circuit part CI1 when the pair of insulation sheets 10s and 20s are viewed in plan.SELECTED DRAWING: Figure 3 |
