PROBLEM TO BE SOLVED: To provide a solenoid valve capable of forming a flow passage with high precision without increasing the number of parts. SOLUTION: This solenoid valve has a pipe 30, a valve seat 40 having a valve seat face 44 opening a valve hole 42, a valve element 62 arranged to oppose an opening of the valve hole 42 on the valve seat face 44 in the inside of the pipe 30, an elastic body 70 applying force to the valve element 62 to move in a first direction being either of direction in which it approaches the valve seat 40 and direction in which it leaves the valve seat 40, and a coil 90 for generating magnetic field by flow of current and generating electromagnetic attraction force for moving the valve element 62 in a second direction being opposite to the first direction by magnetic induction. The pipe 30 and the valve seat 40 are mutually joined with a clearance 50 in at least one section to form the flow passage by the clearance 50. COPYRIGHT: (C)2007,JPO&INPIT
