PROBLEM TO BE SOLVED: To attain the improvement of impact resistance and reliability and the simplification and cost down of the signal processing circuit. SOLUTION: A pressure-sensitive switch PSS for sitting detection is provided with a 1st film 1 of an insulating body equipped with a 1st electrode 1a, a 2nd film 3 equipped with a 2nd electrode 3a on a face confronted with the 1st electrode 1a while facing the 1st film 1, sheet-shaped switches 1-3 interposed between the 1st and 2nd films 1 and 3 while having a spacer 2 of the insulating body, for forming a plurality of mutually separated voids 2a between 1st and 2nd electrodes 1a and 3a, and 1st and 2nd lead wires 4a and 4b connected to the 1st and 2nd electrodes 1a and 3a. In that case, any one of 1st and 2nd films 1 and 3 is polyethylene naphthalate film. |
