    • A crush type pressure detecting device less in occurrence of malfunction, simple in structure, and inexpensive to manufacture is presented. On a crush plate 120 made of ceramics or the like, a conductor path 130 is formed, for example, in linear or U-shape, and electrodes 131 are provided at both ends. Both ends of the crush plate 120 are inserted into a holder 110 made of plastic or printed board so as to support at both sides. An opening 111 is provided in the holder 110 to expose the electrode 131, thereby obtaining a crush type pressure detecting device 100 of the invention. Terminal plates 140 are connected to the electrodes 131 of this detecting device 100, and the terminal plates 140 are used as mounting members, and are disposed in contact with the object to be detected, for example, the outer wall of a housing 210 of a rechargeable battery 200. One terminal plate 140 is connected to the current collector in the housing 210, and other terminal plate 140 is left over outside the housing as an output electrode 240, and the rechargeable battery 200 having the crush type pressure detecting device 100 according to the invention is obtained.
