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.
