PROBLEM TO BE SOLVED: To provide a compact solenoid valve device as compared with a solenoid valve device which controls conventional hydraulic equipment. SOLUTION: The solenoid valve device comprises a coil 21 which generates magnetic force by energization, a cylindrically shaped magnetic sleeve 51 which pierces the coil 21 in the axial direction, a plunger 61 which is freely movably guided in the axial direction by energization or non-energization to the coil 21 stored inside the magnetic sleeve 51 and a valve mechanism 30 driven by reciprocation of the plunger 61 and the magnetic sleeve 51 is composed of magnetic materials and a non-magnetic sleeve 53 is provided by non-magnetic materials between the magnetic sleeve 51 and the plunger 61.
