Abstract

The light source unit comprises a light source emitting visible light and light of a non-visible wavelength; a rod-like light guide at the end of which the light source is provided and within which incident light from the light source is propagated in the long axis direction; a reflector that is linear along the long axis direction and provided on the contour surface of the light guide; and a support member encompassing the reflector and light guide, having a given width in the direction perpendicular to the long axis direction, and provided with an opening extending along the long axis direction. The reflector and support member are formed by a reflecting material containing a substance reflecting the light of a non-visible light wavelength and reflecting the visible light and light of a non-visible light wavelength.
