PROBLEM TO BE SOLVED: To effectively suppress occurrence of operating noise while ensuring an adequate strength for making an electric contact reliable, reduce the parts count in setup, and produce a solenoid-operated fuel-injection valve compact in size, in which a resin mold is provided for embedding at least partly a solenoid housing and the front of an inlet pipe extending rearward from the solenoid housing, the front of the valve housing is fit fluid-tight in a fitting hole of an intake-path-forming member, and a fuel distribution pipe is fit fluid-tight in the rear of the inlet pipe. SOLUTION: The resin mold 7 is formed of two layers of a 1st resin mold layer 7a covering at least partly the solenoid housing 25, and at the same time constituting partly an incoming coupler 40, and a 2nd resin mold layer 7b covering the 1st resin mold layer 7a. A support part 57 with a supporting surface 58 for the fuel distribution pipe 53 is provided integrally with the 2nd resin mold layer 7b formed of a material having a lower bending strength than that of the 1st resin mold layer 7a.
