To provide a solenoid valve which enables a plunger to move in an axial direction stably and smoothly.SOLUTION: A solenoid valve 1 includes: a solenoid part 3 including a stator 32; a plunger 4 which is disposed within the solenoid part 3 and contacts with or separates from the stator 32 by electromagnetic force; a bush 9 disposed between an inner peripheral surface of the solenoid part 3 and an outer peripheral surface of the plunger 4; and a valve body 22 which is reciprocated by motion of the plunger 4 to open or close. Spaces S1, S2 are formed at both sides of the plunger 4 when viewed in a moving direction. The inner diameter side of at least one end part of the bush 9 has an inner inclined surface 9a formed so as to expand its diameter to one S1 of the spaces.
