ABSTRACT:
An EL lamp has an EL light emitting part and a connector part which is connected to both electrodes of the EL light emitting part and is formed so as to be attachable to and detachable from a power supply outlet. The EL light emitting part is flat-plate-shaped and has a reinforcement to give to the EL lamp a mechanical strength against a bending load applied when repeatedly attaching and detaching the EL lamp to and from an outlet while the reinforcement is held by human fingers. Accordingly, the EL lamp is not easily broken by an external force, can be portable, and can withstand frequent attaching and detaching to and from a power supply outlet. The EL lamp can be constructed to enable changing of the illuminating direction of the EL lamp freely in desired directions. The lamp is convenient for use in an automobile having a power supply outlet with a recess into which a connector part of the EL lamp is engaged.
