A solenoid valve has a spool is moved via a rod. A breathing hole penetrates a sleeve in a radial direction and allows an inner space of a housing part to communicate with the outside when at least a circular columnar plunger is in a predetermined region provided on a solenoid case side of the sleeve. A through-hole is formed in an axial direction at the center axis of the circular columnar plunger. The rod is configured such that an opposing groove portion passes through the center of the circular columnar plunger in the radial direction and penetrates both radial sides provided with cutout portions of the rod formed at an opposing end portion facing a circular columnar plunger side and an inner surface of the opposing groove portion formed in a symmetrical arc shape as viewed in the radial direction.
