Abstract
A solenoid includes a coil configured to generate magnetic force when a current flows therethrough; a stator core provided inside the coil, the stator core being configured to be excited by the magnetic force of the coil; a plunger received in a plunger chamber formed inside the stator core, the plunger being configured to move toward an attraction part in the plunger chamber by the magnetic force of the coil; a shaft provided to be able to move, together with the plunger, along axial direction; and a filter provided inside the stator core. The filter is provided on a side of the attraction part from the plunger and in an axial range where the coil is provided.
