An electrical steering column lock includes a locking guide that advances and retreats with respect to a lock ring by a driving part, and a lock bar that advances and retreats toward and from the locking guide within a predetermined distance in the same direction as that of the locking guide. The lock bar has a leading end disposed toward the lock ring, and is elastically biased toward the locking guide in a lock ring direction. One side of the locking guide is provided with a protrusion. A slider that advances toward the locking guide or retreats from the locking guide is positioned facing the protrusion, and the slider is provided with a grooved part into which the protrusion is inserted.
