<P>PROBLEM TO BE SOLVED: To provide a solenoid valve suppressing self-excited oscillation by a simple configuration. Ž<P>SOLUTION: In the solenoid valve 100A, a valve seat 118b is interposed in a working fluid passage. A valve element unit 111 is provided movably in the first direction toward the valve seat 118b and the second direction separated from the valve seat 118b, inhibits the communication of the working fluid passage when a tip 114a is seated on the valve seat 118b, and communicates the working fluid passage when the tip 114a is separated from the valve seat 118b. A needle 116 which is a magnetic material is provided in the valve element unit 111 so as to be separated from the tip part 114a. Due to a flow of magnetic flux generated by supply of electric current to a coil 130, a bottom part 120e applies first suction force to the needle 116, and an upper end part 110e applies second suction force to the needle 116. The needle 116 is moved by resultant force of the first suction force and the second suction force. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
