Abstract: To yield fixed output as electrical signal when any positions of volume space is subjected to external pressure and the external pressure is detected. A contact detecting device includes a mounted base 60 with a predetermined shape, a design foam 10 that is bonded to the mounted base and covers it, and a limiter 7 that is mounted on the mounted base 60 or the design foam 10. The contact detecting device further includes a predetermined volume space 4 defined by the mounted base 60, the design foam 10, and the limiter 7. The contact detecting device further includes a sensor SEN that detects external pressure applied to the volume space 4 through the determination of the physical variation of the volume space 4. The physical variation of the volume space 4 is detected through the sensor determining, for example, variation in flow rate, flow velocity, or volume. In particular, the contact detecting device detects two-dimensional or three-dimensional contact on any position.

Abstract: A contact detection device detects pressure over a wide range, be applied to even a three-dimensional structure, and detect predetermined contact pressure or more. A volume space 4 is between a base 1 that is composed of a foamed synthetic resin 10 with a particular shape and the foamed synthetic resin body 10 that is composed of the foamed synthetic resin with a particular shape and covers the foamed synthetic resin body 10. The volume space 4 is on either or both of the base 1 and the foamed synthetic resin 10. Air in the volume space 4 is prevented from leaking trough the base 1 and the foamed synthetic resin 10 to open air. At least one flow sensor 70 detects flow rate (liter/second) of air that flows from the volume space 4 to open air.
