Provided is a variable-capacity compressor control valve with a simple configuration that can secure the size of a sub valve element portion of a sub valve element, which is adapted to open or close an in-valve release passage, and can improve the actuation property and reduce the size of the control valve. The sub valve element (17) is integrated with the plunger (37) for moving the main valve element (15) in the direction to open or close a valve orifice so that the sub valve element (17) always moves together with the plunger (37). The sub valve element (17) is securely inserted in the plunger (37).
