A capacity control valve for controlling a flow rate or pressure in a control chamber according to a valve opening degree of a valve section, comprising: a valve main body having a first valve chamber communicating with a first communication passage through which a fluid at control pressure passes and having a first valve seat surface and a second valve seat surface, a second valve chamber having a valve hole communicating with the first valve chamber and communicating with a second communication passage through which a fluid at discharge pressure passes, and an interior space communicating with a third communication passage through which a fluid at suction pressure passes; a pressure sensitive body arranged in the interior space and having a communication part communicating with the interior space on a free end part side moving so as to extend and contract in response to the suction pressure; a valve body including at least an intermediate communication passage for communicating the first valve chamber and the interior space, a second valve part for opening and closing the valve hole for communicating the first valve chamber and the second valve chamber by separating from and contacting with the second valve seat surface, a first valve part for opening and closing a fluid passage between the intermediate communication passage and the first valve chamber by separating from and contacting with the first valve seat surface in conjunction with the second valve part in the opposite direction thereto, and an abutment part abutting the free end part of the pressure sensitive part; and a solenoid section attached to the valve main body and actuating the respective valve parts of the valve body so as to be opened and closed, and a maximum opening area (S2max) of the first valve part is smaller than an opening area (Sa) of the intermediate communication passage, characterized in that the first valve seat surface consists of an inner wall part (31A1) extending in an axial direction and an end surface (31A2) extending in a radial direction, the first valve part has a first valve part surface (21H2) extending in the radial direction and opposed to the end surface (31A2) and a tapered surface (21H1) formed in the axial direction and opposed to the inner wall part (31A1), wherein the diameter of the tapered surface (21H1) is increased along the axial direction starting from an inner diameter part corresponding to the diameter of the first valve part surface (21H2), and an axial gap part (ΔL2) whose size is changed according to the stroke of the valve body is formed between the first valve part surface (21H2) and the end surface (31A2), and a radial gap part (ΔR) whose size is changed according to the stroke of the valve body is formed between the tapered surface (21H1) and the inner wall part (31A1). a valve main body having a first valve chamber communicating with a first communication passage through which a fluid at control pressure passes and having a first valve seat surface and a second valve seat surface, a second valve chamber having a valve hole communicating with the first valve chamber and communicating with a second communication passage through which a fluid at discharge pressure passes, and an interior space communicating with a third communication passage through which a fluid at suction pressure passes;
