とを特徴とする電磁弁。 A valve body 16 is provided to open and close a liquid passage 14 formed in the body 11, and the valve body 16 is closed via a rod 15 when a solenoid coil 22 is energized. A first spring 19 that biases the valve body 16 in the opening direction and a second spring 23 that biases the valve body 16 in the opening direction are provided. is formed of a shape memory alloy that increases the opening force of the valve body, is disposed in the fluid passage, and has one end engaged with the valve body 16, so as to control the temperature of the fluid flowing in the fluid passage and the temperature of the valve body 16. Further, the valve body 16 and the rod 15 that actuates the valve body are made of a heat conductive metal, and the valve body 16 and the rod 15 have good mutual heat conduction. In addition, the valve body 16 has an outer circumferential surface elongated in the axial direction so as to be close to the inner surface of the second spring 23, and the outer circumferential surface of the second spring 23 includes:
A solenoid valve characterized in that a sleeve 24 made of a thermally conductive metal is disposed in close proximity and the sleeve 24 is connected and fixed to a stator that generates heat by the solenoid coil 22.
