Abstract
Provided is a variable-capacity compressor control valve that can secure the attraction force of an electromagnetic actuator and can improve the actuation property without increasing the body size. A sub valve element or a cylindrical upper end portion thereof, which is a magnetic body made of the same magnetic material as or a different magnetic material from that of a plunger, is fixed to the inner periphery of the upper end portion of the plunger that is opposite an attractor.
