PROBLEM TO BE SOLVED: To provide a solenoid valve capable of restricting deterioration of magnetic efficiency without increasing costs. SOLUTION: A metal part 31 is formed by connecting a core 45 and a yoke 46 to each other with an articulated section 63, and a synthetic resin is adhered to the periphery of the metal part 31 for fixation to integrally form a bobbin 81. The inside surface of the metal part 31 is cut by counter boring, and cuttable parts of the articulated section 63 are cut to form clearance parts 71 separating the core 45 and the yoke 46 from each other. Residual parts of the articulated section 63 are left to form connecting parts 72 for connecting the core 45 and the yoke 46 to each other, and the clearance parts 71 and the connecting parts 72 are formed each other in the circumferential direction. The articulated section 63 is reinforced by the synthetic resin of the peripheral part, and a distance between the core 45 and the yoke 46 and coaxiality thereof are maintained by the connecting parts 72.
