PROBLEM TO BE SOLVED: To fix a main valve part and a solenoid part with a fixing member while adjusting the length of the core stroke of a movable core. SOLUTION: An O-ring 26 is disposed between the main valve part 11 and the solenoid part 31. When the main valve part 11 is fixed to the solenoid part 31 by the fixing member 51, the O-ring 26 is elastically deformed, and the main valve part 11 and the solenoid part 31 are moved in the directions approaching and separating from each other to adjust the length L1 of the stroke of the core. When the length L1 of the stroke of the core is equal to the length L2 of the stroke of the valve, the contact parts between the front end of an extended part 51b and the pair of outer surfaces of a guide ring 34 are joined to each other by laser welding.
