To solve the problem of being forced in a shutting-out state up to waiting for the arrival of an expert dealer, without having a means for operating a bolt member (a dead bolt) from an external part, when failure is caused in a control circuit and a mechanism, in a conventional electronic lock.

This emergency unlocking device of the electronic lock has a lock lever for putting its bolt member in a locking state by engaging the bolt member in a receiving mechanism of the bolt member taken in and out of an electronic lock body; and its lock lever releases the locking state by sliding or rotating by input from the outdoors. The electronic lock body is fixed to an installation plate for pivotally moving in the indoor side direction to a baseplate fixed to an indoor side surface of a door.
