PURPOSE: A solenoid valve is provided to improve durability and the reliability of operation by improving the structure. CONSTITUTION: A solenoid valve is installed by connecting a fluid inlet hole(31) and a fluid outlet hole(31) of a fluid block(33) to a fluid line on which a certain fluid flows, so the flow of the fluid is controlled by the operation of the solenoid valve. If a certain air is flowed in via an open air inlet hole(35), a piston(38) is shifted upward. A fluid passing hole(42) formed between the fluid inlet hole and the fluid outlet hole is opened by the upward shifting of a closing member(40) formed on the end of a piston rod(39) connected to the piston. Herein, a certain fluid flowed in via the fluid inlet hole is discharged via the fluid outlet hole by passing the fluid passing hole.
