Abstract

A light emitting diode array has light emitting dots arranged in a line and is characterized in that a semiconductor substrate of a chip constituting the light emitting diode array has a Dovetail grooved mesa shape on a chip end face opposed to an adjacent chip and arranged in a direction perpendicular to an arranging direction of light emitting diodes. A light emitting portion can be protected from chipping even when a length from the light emitting portion of the light emitting diode array to a chip end portion is shorter than the size of a chipping portion.
