Abstract
A panel of an electronic device on which an indicator is mounted is provided with an insertion hole therethrough. The indicator is composed of a light guide with one end surface exposed to a front surface side of the panel and another end surface projecting to a rear surface side of the panel, through the insertion hole, and a light emitting unit provided on the rear surface side of the panel such that a light emitting portion thereof is opposed to the other end surface of the light guide. Further, the light guide is composed of a light transmitting elastic body having a uniform cross section, and fixed by an outer peripheral surface thereof near the one end surface being in pressure contact with an inner peripheral surface of the insertion hole.
