PROBLEM TO BE SOLVED: To provide a solenoid valve of high operational reliability.SOLUTION: In a solenoid valve 1 including a cylinder 21 in the inside of which a valve chamber 23 is formed, a gas flow channel communicating the inside and outside of the cylinder 21, and including a lead-in passage 36 for leading a high-pressure gas into the valve chamber 23 and a lead-out passage 24 for leading the led-in high-pressure gas, out of the valve chamber 23, a coil 71 disposed in a state of being wound on an outer periphery of the cylinder 21, a plunger 72 disposed in the inside of the valve chamber 23 and moving in the valve chamber by power supply to the coil 71, and a valve element 52 for opening and closing the gas flow channel linked with the plunger 72, the plunger 72 includes a first split body 110 accommodating the valve element 52, and having a boundary portion coming in contact with a part at a side opposite to a valve opening direction, of the valve element 52 in opening the gas flow channel, and a second split body 120 fixed to the first split body 110 in a state of accommodating the valve element 52 between the boundary portion and the second split body. |
