ABSTRACT A light transmitting rod (22) on an end surface of which is disposed a reflecting mirror (26) and on the other end surface of which is mounted a lamp (44) as a light source for emitting light into the light transmitting rod (22) is attached to a base (12), and a diffusion stripe (24) is formed by applying fine powder having a high refractive index to the outer circumferential surface of the light transmitting rod (22) in a rectilinearly pin- striped manner along the axial direction thereof, whereby an even linear light profile of high luminous energy level and having uniform luminous energy as well as no polarization which is also irradiation light having a small light distribution beam angle and being substantially parallel rays can be obtained. As a result, it is possible to provide a light source unit used suitably in business and office machines such as an image scanner, an optical printer, a monochromatic copying machine, a color copying machine, a facsimile machine and the like.
