PROBLEM TO BE SOLVED: To provide a miniatulizable solenoid valve. SOLUTION: A core 22 is inserted into the lower part of a bobbin 13, and a plunger 24 is vertically movably stored in an upward storing space 23. The plunger 24 is formed of a magnetic substance in a hollow shape opening upward, and a magnetic delivery section 35 of a yoke 34 is inserted into an insertion section 33 opening on the upper end side. The yoke 34 comprises a base section 51 arranged on a solenoid 16 via a collar section 43, the cylindrical magnetic delivery section 35 extending to the lower side than the inner edge of the base section 51, and a tip 52 at the lower end of the magnetic delivery section 35. A facing surface 53 facing the magnetic delivery section 35 is installed on the inside surface of a side wall part 31 of the plunger 24 constituting the insertion section 33, and magnetism from the yoke 34 excited by the solenoid 16 is delivered to the plunger 24 via the facing surface 53 facing the magnetic delivery section 35.
