A light source apparatus includes a light source, and a light guide member which a light beam from the light source enters. The light guide member includes a reflector configured to reflect the light beam on a first surface of the light guide member, and a separator configured to separate the light beam on a second surface of the light guide member different from the first surface into a reflected light beam and a transmitting light beam. The light beam incident on the light guide member is reflected by each of the reflector and the separator and propagates in a first direction. Among light beams propagated through the light guide member, the light beam separated by the separator is emitted from the light guide member. An incident angle of the light beam incident on the second surface of the light guide member is smaller than a critical angle.
