PURPOSE: A solenoid valve is provided to improve the suction force and responsibility of the fluid by increasing the contact area of the fluid. CONSTITUTION: In a solenoid valve, a plunger(4) moves to left and right by an excitation and a spring(9) of the solenoid valve to make packings(10,11), which is installed to both sides of the plunger, open and close an inlet port(6) and a fluid passage(8) respectively. A plurality of grooves(16) is formed to a right surface of the plunger with same diameter. A moving speed of the plunger is increased by the improved suction force and responsibility of the fluid.
