The purpose of the present invention is to provide a capacity control valve with which it is possible to efficiently discharge a liquid refrigerant irrespective of the pressure of a suction chamber. A capacity control valve (1) includes: a valve main body (10) having a first communication passage (11), a second communication passage (12), a third communication passage (13), and a main valve seat (15a); a valve body (20) having an intermediate communication passage (26), a main valve part (21b), and an auxiliary valve part (23d); and a solenoid (30) equipped with a first plunger (34) having a first rod (33), and a second plunger (35) having a second rod (36), the first rod (33) opens and closes the main valve part (21b), and the second rod (36) opens and closes the auxiliary valve part (23d).
