PROBLEM TO BE SOLVED: To stably perform fuel injection by stabilizing an operation of a high pressure injector even at the time of a cold starting. SOLUTION: In a high pressure injector for a high pressure fuel injection device for pressing a pressure intensifying piston by delivering operating oil O to a pressing chamber by opening a poppet valve 23, pressurizing fuel of a pressure intensifying chamber by the pressure intensifying piston and injecting pressurized fuel via a needle valve, the injector is constituted by being provided with a heating means 28 heating operating oil O accumulated within an armature chamber 27 faced by an armature 22 of a solenoid part 20. |
