PROBLEM TO BE SOLVED: To easily confirm disconnection of an inner circuit by connecting a resistor to a first wiring wire connected to an input terminal and to a second wiring wire connected to an output terminal, and connecting a switch which switches on/off by pressure between the input terminal, the output terminal, and the resistor to the wiring wire. SOLUTION: A switch having comb teeth-shaped lower contacts 3a-3l, a disconnection detecting resistor 1, and a lower electrode circuit 4 are formed on the one surface of a lower film 6 having a shape branched like a tree branch to constitute a lower electrode sheet 8. Upper contacts matching the lower contacts 3a-3l when stuck to the lower electrode sheet 8 are formed on the one surface of an upper film, the upper contacts and the lower contacts 3a-3l are faced through a spacer so as to form a space, the base part of the lower electrode circuit 4 is used as an input terminal and an output terminal to constitute a sealing sensor. Disconnection is easily detected without removing the seating sensor. |
