Abstract
A light source apparatus includes a circuit board on which a light source unit including a vertical-cavity surface-emitting light source and a package that houses the vertical-cavity surface-emitting light source is mounted, an optical element holder that holds a plurality of optical elements including at least a coupling lens, and an intermediate holder that is arranged between the circuit board and the optical element holder. The intermediate holder is joined to the circuit board to cover an area of the circuit board on which the light source unit is mounted to thereby make contact with the package such that the vertical-cavity surface-emitting light source is positioned and fixed and joined to the optical element holder to thereby position the optical elements to the vertical-cavity surface-emitting light source.
