Abstract
It is an object to provide a technique of achieving a high in-plane mounting density of a laser light source element and capable of adjusting a position of a lens for each laser light source element with a high degree of accuracy. A laser light source apparatusincludes: a base; a plurality of semiconductor laser elements; a plurality of lenses parallelizing laser light being output from the plurality of laser light source elements; a spacer disposed on the upper surface of the base; and an adhesive agent fixing the plurality of lenses to the spacer. The spacer includes, for each of the lenses, an annular support surface and a wall, and the wall has a clearance groove formed along a direction connecting diagonal points of the lattice points.
