PROBLEM TO BE SOLVED: To provide a fuel injection valve including a sensor element detecting fuel pressure capable of suppressing an increase in the number of components, suppressing an increase in machining cost, and relaxing the mounting position accuracy of the sensor element. SOLUTION: The fuel injection valve inserted and arranged in the cylinder head of an internal combustion engine and injecting high-pressure fuel from a nozzle port includes a body 40 internally forming a high-pressure passage 422 extending in an insertion direction into the cylinder head and circulating high-pressure fuel toward the nozzle port. The high-pressure passage 422 is formed in a position decentered with respect to the shaft center J1 of the body 40, and a sensor chip 81 (sensor element) outputting an electric signal according to the amount of distortion of the outer peripheral surface of a thin-walled portion 41 is attached to the outer peripheral surface of the thin-walled portion where the body 40 around the high-pressure passage 422 becomes thinnest.
