PROBLEM TO BE SOLVED: To facilitate mobility of fluid in a solenoid valve when opening and shutting the valve by separating and connecting a valve body with respect to a valve seat with magnetic force of a solenoid coil. SOLUTION: The solenoid valve is provided with a valve main part 1, the solenoid coil 2, a suctioner 3, the valve body 4, a plunger 5 connecting with the valve body 4, a valve-seat sheet member 6 forming the valve seat 61, and a coil spring 7 arranged between the suctioner 3 and the plunger 5. When electricity is applied to the solenoid coil 2, a magnetic force caused by electric conduction of the solenoid coil 2 is generated on the suctioner 3, and the plunger 5 moves toward the suctioner 3 while resisting to urging force of the coil spring 7. The valve body 4 moves toward the valve seat 61 of the valve-seat sheet member 6 together with the plunger 5, the valve body 4 is firmly touched with the valve seat 61 of the valve-seat sheet member 6, and the solenoid valve performs a closing-valve operation. A clearance 17 is formed between a pipe portion 15 and the suctioner 3, and caulked portions 20 are provided in a plurality of places by caulking so as to maintain the clearance.
