PROBLEM TO BE SOLVED: To improve sliding performance in a solenoid part and to accurately control the output pressure in regard to a solenoid valve device including a linear solenoid valve. SOLUTION: This solenoid valve device includes a linear solenoid valve 14a including: a linear solenoid part 30 for making a shaft part 58 slide with excitation of a coil; a valve body 44 including a built-in spool 28 capable of sliding with slide of the shaft part 58; a chamber 60e provided in the valve body 44, adjacent to the linear solenoid part 30, surrounding the shaft part 58, to store a fluid to be led into there; a port 60d provided in the chamber 60e to discharge the fluid stored in the chamber 60e. The port 60d is opened in the inner surface of the chamber 60e in an upper side in the vertical direction than a liquid level in the state of soaking a part of the shaft part 58 in the liquid level of the fluid stored in the chamber 60e.
