PROBLEM TO BE SOLVED: To provide an optical pressure sensor capable of easily manufacturing and surely adaptable to the pressure to be measured with a simplified structure. SOLUTION: The central axis of the tip surface of the rod lens 7 is made to offset from the central axis of the reflection surface 27, light is emitted from the tip surface of the rod lens 7 to the reflection surface 27. A part of the reflected light from the reflection surface 27 is received at the tip surface of the rod lens 7. The pressure at the observation point is converted into the received light amount at the tip surface of the rod lens 7. COPYRIGHT: (C)2006,JPO&NCIPI
