PROBLEM TO BE SOLVED: To provide a fuel injection valve inhibiting enlargement of a body on which a fuel pressure sensor is attached, and simplifying an electrical connection structure of the fuel pressure sensor in the fuel injection valve including the fuel pressure sensor. SOLUTION: This fuel injection valve includes: the body 40 which has high pressure passages 421, 422 to introduce high pressure fuel toward an injection hole 22 formed therein; a stem 81 (strain generating body) attached to the body 40, and elastically deformed by receiving pressure of the high pressure fuel; and a strain gauge 82 (sensor element) attached to the stem 81 and converting magnitude of strain generated in the stem 81 to electrical signal. The fuel pressure sensor 80 is mounted on the body 40 by welding the stem 81 on the body 40. COPYRIGHT: (C)2011,JPO&INPIT
