To provide a capacity control valve having good responsiveness for a differential pressure. A capacity control valve V includes a valve housing 10, a primary valve 50 opened and closed by a driving force of a solenoid 80, a pressure-sensitive valve 53 opened and closed by a pressure of a pressure-sensitive chamber 40, and a differential pressure valve 90 opened and closed by a differential pressure valve body 91 moved by a pressure. A control port 14 and a suction port 13 can communicate with each other through an intermediate communication path 55 by opening and closing the pressure-sensitive valve 53. An adapter 70 is provided with an accommodation portion 70d accommodating a differential pressure valve body 91, a pressure introduction path 70e communicating the control port 14 with the accommodation portion 70d, and a differential pressure communication path 70f communicating the control port 14 with the suction port 13 when opening the differential pressure valve 90. A first urging member 92 and a second urging member 93 are interposed in the accommodation portion 70d on both sides of the differential pressure valve 90 in an opening and closing direction with the differential pressure valve body 91 interposed therebetween.
