A laser module 10 is provided with: a plurality of laser elements 1 that emit optical beams, respectively; a collimating optical system 3 that parallelizes the optical beams thus emitted; and a light collecting optical system 4 that collects the optical beams thus parallelized. The laser elements 1 are photonic crystal surface-emitting laser (PCSEL) elements, respectively. The laser elements are disposed in a hexagonal lattice shape on a same plane of a base 2.
