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 apparatus 1 includes: a base 30; a plurality of semiconductor laser elements 101 to 104 arranged on the upper surface of the base 30 and also on lattice points which are intersection points between an x axis group and a y axis group, in which an x axis and a y axis directed to a direction intersecting with the x axis are arranged, respectively; a plurality of lenses 41 to 44 parallelizing laser light being output from the plurality of laser light source elements 101 to 104; a spacer 20 disposed on the upper surface of the base 30; and an adhesive agent 50 fixing the plurality of lenses 41 to 44 to the spacer 20. The spacer 20 includes, for each of the lenses 41 to 44, an annular support surface 20b and a wall 20c, and the wall 20c has a clearance groove 20d formed along a direction connecting diagonal points of the lattice points.
