PROBLEM TO BE SOLVED: To improve the fixation strength of a valve seat member by forming a chamfered part on the outer diameter end face of the valve seat member and minimizing the plastic deformation amount of a valve by rolling-caulking the chamfered part when fixing the valve seat member fitted to and inserted into the inner diameter of the valve. SOLUTION: This solenoid valve is provided with a solenoid coil provided around a fixed iron core, a movable iron core movable by an attraction force by the fixed iron core and the solenoid coil, and the valve for controlling a flow of fluid by the movable iron core. When a first valve seat and a second valve seat fitted to and inserted into the inner diameter of the valve part are fixed, the chamfered part is formed on the outer diameter end face of the valve seat member, and the chamfered part is fixed to the valve by rolling-caulking.
