PROBLEM TO BE SOLVED: To prevent the entry of brake liquid mist into a substrate chamber where an electronic substrate is disposed. SOLUTION: A coil chamber 52 where a coil portion 31 of a solenoid valve 3 is disposed and the substrate chamber 53 where the electronic substrate 6 is disposed are defined. The coil chamber 52 and an outside space are communicated through a ventilating hole 54, and an atmosphere chamber 22 and the coil chamber 52 are communicated through a reservoir communicating hole 12. An opening portion on a coil chamber 52 side at the ventilating hole 54 and an opening portion on the coil chamber 52 side at the reservoir communicating hole 12 are oppositely disposed, thereby making the brake liquid mist jetted from the reservoir communicating hole 12 easily reaching the ventilating hole 54.
