PROBLEM TO BE SOLVED: To provide an improved fuel injection valve strong against use in a high temperature atmosphere. SOLUTION: This fuel injection valve 1 is formed by being fixed to a tip part of an injector body 2 by a retaining nut 4, and is constituted so as to inject fuel from a nozzle port 3B arranged in a tip part 3A of a nozzle body 3. A gasket integrated tube 40 composed of a material having heat conductivity larger than the nozzle body 3, is fitted to the tip part 3A of the nozzle body 3 so as to closely contact with an outer peripheral surface of the tip part 3A of the nozzle body 3. The gasket integrated tube 40 extends up to the vicinity of the nozzle port 3B of the nozzle body 3 on one end, and the other end appears outside a cylinder 100 in a state of installing the fuel injection valve 1 in the cylinder 100.
