There is provided a spread illuminating apparatus to improve the coupling efficiency between members constituting a light source. The light source comprises a bar-like light conductive member and spot-like light sources. The spot-like light sources are mounted and soldered on an FPC, the light conductive member is fitted between the spot-like light sources, and ends of the light conductive member face light emitting surfaces of the spot-like light sources. The FPC has a deformed portion shaped U and forming an open area. An elastic force is generated in the longitudinal direction when the open area is expanded, by inserting the light conductive member whose length is larger than a distance between the spot-like light sources, between the spot-like light sources. This elastic force makes the light emitting surfaces of the spot-like source press on the ends of the light conductive member, and the coupling efficiency therebetween is improved.
