PROBLEM TO BE SOLVED: To provide a pressure sensor capable of easily manufacturing and surely adaptable to the pressure to be measured with a simplified structure. SOLUTION: The 2-core rod lens 5 of a lengthy shape, the end surfaces of which are connected with the tips of the emission light fiber 3 and the reflection light fiber 7 respectively, and the another ends are opened. The pressure sensing part 19 is arranged facing to the another end of the 2-core rod lens 5 while being provided with a reflection surface 21 which is deformed convexly under the pressure of the observation point. The central axis of the another end of the 2-core rod lens 5 is made offset with the center line of the reflection surface 21. COPYRIGHT: (C)2006,JPO&NCIPI
