That is, the light transmitting section 5 is configured to transmit the light emitted from the light source 4 to the linear light emitting section 3, that is, to not emit the light to the outside at this portion. Is disposed in the apron E inner part for holding the apron. The light transmission section 5 has a structure in which, for example, a light-emitting light reflecting layer or a reflective protective layer is provided on the entire circumference in a linear light emitting section composed of a light transmission tube. For the purpose of protection, it can be inserted into a transparent resin pipe or the like, or can be covered with a transparent heat-shrinkable tube to protect the light transmission tube and seal the entire linear light emitting portion.

Since the lighting device is provided as a lighting device, it is possible to perform a shave, wash hair, and the like while checking the face of the user with a brightly illuminated mirror, thereby providing a highly safe lighting device with improved usability. In this embodiment, the linear light-emitting portion 3 is provided inside the counter C. Alternatively, the linear light-emitting portion may be provided as an auxiliary lighting device over the entire length or almost the entire length of the apron portion. Good.
