PROBLEM TO BE SOLVED: To provide a manipulation operation detecting sensor, and a manipulation operation detecting device capable of certainly detecting operation such as crumpling, by a simple structure.SOLUTION: A manipulation operation detecting sensor has a hermetic container 11A filled with gas inside, and deforming a deforming portion 19 by contacting with a contacted body (a hand of a tester, etc.); and a microphone 13 arranged in the inside of the hermetic container 11A, and detecting inner pressure change generated when the deforming portion 19 is deformed. Air can be used for the gas filling in the inside of the deforming portion 19. The pressure in the deforming portion 19 is adjusted by a pressure adjusting portion 15. |
