To provide a control valve for a variable displacement compressor using a diaphragm for a pressure-sensing section, which is capable of sensing suction pressure as absolute pressure. <??>A core 27, a first plunger 26, and a spring 28 of a solenoid are accommodated in a bottomed sleeve 25. A diaphragm 29 is welded to an open end of the bottomed sleeve 25 under vacuum atmosphere, whereby an assembly having a vacuum inside is formed. As a result, suction pressure Ps can be sensed as an absolute pressure with reference to a vacuum. The magnetic gap between the first plunger 26 and the core 27 is adjusted by the amount of press-fitting of the core 27 into the bottomed sleeve 25, and the adjustment of load of the spring 28 incorporated into the bottomed sleeve 25 is made by deforming the bottom of the bottomed sleeve 25 such that it is dented inward. <IMAGE>
