PURPOSE: A solenoid valve for an automatic transmission is provided to prevent performance degradation due to the inflow of foreign materials into the solenoid valve through a discharge port by installing a filter member in the discharge port. CONSTITUTION: A solenoid valve for an automatic transmission comprises a flange(200), a spool, and a driving part(400). The flange comprises a guide hollow part, a supply port(220), a control port(230), and a discharge port(240). The supply port, the control part, and the discharge port are communicated with the guide hollow part. The spool is slidingly installed in the guide hollow part. The driving part is installed at the bottom of the flange and slidingly moves the spool. A filter member is assembled to the discharge port.
