A solenoid valve according to an embodiment of the present invention is installed in a valve block and controls flow between a first flow path and a second flow path of the valve block. The solenoid valve includes: a seat member having an orifice that fluidly connects the first flow path and the second flow path; an armature configured to selectively open and close the orifice through a forward and backward movement so as to selectively form a main flow path connecting the first flow path and the second flow path; a magnet core configured to provide a driving force capable of causing movement of the armature for selective formation of the main flow path; a filter member installed so as to filter out impurities contained in oil flowing between the first flow path and the second flow path; and a check valve structure configured to form a unidirectional auxiliary flow path connecting the first flow path and the second flow path. The check valve structure includes: one or more oil passages provided in the filter member; and a lip seal disposed in a space connected to the oil passage. The lip seal is disposed in a space between the filter member and the valve block so as to be installed in a state supported by the filter member and the valve block.
