A light source apparatus and the like capable of improving the manufacturing yield are provided. The light source apparatus includes a light source, a collimator which is arranged to face the light source and includes a reflection portion for adjusting a focal length of light incident from the light source to the collimator, and a light guide arranged on an emission side of the collimator. The reflection portion of the collimator includes a normal focus area in which the light emitted from the light source and incident to the collimator is converted into substantially parallel light, a long focus area in which the light incident to the collimator is converted into slightly divergent light in comparison with the substantially parallel light, and a short focus area in which the light incident to the collimator is converted into slightly convergent light in comparison with the substantially parallel light.
