In a fuel injection valve installed in a cylinder head to inject fuel from a fuel injection pump into a combustion chamber, a heat insulator placed on the front end surface and outer periphery of the tip of the needle valve case into which the needle valve is inserted is made of ceramic material. The flange portion of the heat insulator is held between the fuel injection valve and the cylinder head via a seal member having heat resistance, heat insulation properties, and relatively flexibility. Fuel injection valve.
