置。[Scope of Claim for Utility Model Registration] 1. An electrostrictive fuel injection valve having an electrostrictive actuator for controlling fuel injection and mounted on a cylinder head facing the combustion chamber of an internal combustion engine, and an electrostrictive fuel injection valve that injects fuel at a predetermined high pressure. An internal combustion engine that includes a pressure accumulation chamber for accommodating the fuel, and a fuel passage that supplies high-pressure fuel in the pressure accumulation chamber to an electrostrictive actuator, and injects an amount of fuel according to the operating time of an electrostrictive actuator. 1. A fuel injection device for use in a fuel injection device, wherein the pressure accumulation chamber is provided in a cylinder head in close proximity to an electrostrictive fuel injection valve. 2. The fuel injection device according to claim 1, wherein the pressure accumulation chamber is formed of a material different from that of the cylinder head and is insert molded within the cylinder head. 3. The fuel injection device according to claim 1, wherein the length of the fuel passage between the pressure accumulation chamber and the nozzle of the fuel injection valve is less than about 90 mm. 4. The fuel injection device according to claim 1, wherein the capacity of the pressure accumulation chamber is about 1000 times or more the large injection amount per one injection cycle of the fuel injection valve.
