The present invention realizes a sealing structure disposed on an outer circumference of a control valve at low costs. A valve body (2) comprises: a body (5) comprising a port (16) into which a refrigerant is introduced, a port (14) from which the refrigerant is discharged, and a valve unit disposed on a main path connecting the ports (14, 16); and a filter member (15) mounted on an outer circumferential surface of the body (5) to cover the ports (14, 16) to restrict infiltration of foreign substances into each port. The filter member (15) comprises: a cylindrical resin material frame assembled to be inserted into the outer side of the body (5) and provided with an annular recess (92) disposed along an outer circumferential surface; a metal or resin material mesh integrated into the frame to restrict a passage of foreign substances; and an O-ring inserted into the annular recess (92) of the frame to perform a sealing function when the valve body (2) is accommodated in a mounting hole of a target device. |
