Abstract
To make it possible to easily produce a solenoid for a solenoid valve at low cost by reducing the number of parts and assembling steps. In a solenoid for a solenoid valve, a pole face is formed on an end wall portion of a magnetic case which covers a bobbin around which a coil is wound, thereby allowing the end wall portion to function as a stationary core, an end surface of a moving core inserted in center holes of the bobbin and the magnetic plate is set opposed to the pole face, and the moving core is adsorbed by the end wall portion by energizing the coil.
