Abstract
Disclosed is a light source module which does not require rigorous adjustments of the light direction and is free from luminance unevenness. Specifically disclosed is a light source module (1) which comprises a light-emitting element (40), and a light direction changing element (10) which is composed of a transparent resin and discharges the light emitted from the light-emitting element (40) toward the lateral direction. The light direction changing element (10) contains not less than 0.01% by weight but not more than 0.1% by weight of a light-diffusing agent (14) per 100% by weight of the transparent resin.
