Abstract
A valve seat, which a valve body of a movable core sits on, protrudes from an outside region of the valve seat located at an end of a columnar body toward the movable core. A gas flow passage in the movable core has: an inflow passage extending on a stationary core side in the direction in which the movable core moves; and two or more outflow passages branched on a valve body side from the inflow passage. A protrusion height of the valve seat is 0.3 times or more an inner diameter of the outflow passages. A gas accumulation space includes: a region located away from the movable core by a distance 0.5 times or more the inner diameter of the outflow passage; and a region located away from the movable core by a distance greater than or equal to the inner diameter of the outflow passage.
