A normally closed first on-off valve that opens when the excitation coil is released, and a normally closed first on-off valve that closes when the plunger is attracted toward the core when the excitation coil is energized, and the valve body is pressed against the valve seat member. In the electromagnetic valve in which a second on-off valve of the type is vertically arranged, a valve seat member of the second on-off valve and a port member forming a fluid passage are press-fitted into the through hole of the core, and the port member is press-fitted into the through hole of the core. A solenoid valve, characterized in that a protruding portion of the member protruding from the core is slidably inserted into a through hole bored in the center of a plunger of the first on-off valve. (2) A plate-shaped valve body pressing member that presses the valve body of the first on-off valve is placed close to an end of the protrusion of the port member at an end of the through hole of the plunger of the first on-off valve. The valve body pressing member is fixed, and at least one oil passage is bored in the valve body pressing member at a position apart from the central pressing part that presses the valve body, and when the excitation coil is energized, the protruding part 2. The electromagnetic valve according to claim 1, wherein an end portion of the first on-off valve is configured to abut against the valve body pressing member, and a plunger of the first on-off valve does not abut against the core.
