PROBLEM TO BE SOLVED: To reduce the sliding resistance of a moving core which is displaced under the excitation effect of a solenoid. SOLUTION: A solenoid valve comprises a valve body 18 having first to third ports 12, 14 and 16, a bonnet 20 integrally connected to an upper part of the valve body 18, a bobbin 54 which is disposed inside the bonnet 20 with a coil 52 wound therearound, projecting parts 60a, 60b, 60c and 60f projected by the predetermined length from an inner circumferential surface of a hole part 55 of the bobbin 54, and a moving core 58 inserted in the hole part 55 of the bobbin 54 in a displaceable manner along the axial direction.
