Abstract
A semiconductor laser element includes a substrate having a first main surface and a second main surface; a semiconductor layered body including an active layer, the semiconductor layered body being disposed on the first main surface; and a plurality of sub-patterns that, when combined, form an integrated pattern that allows reading of predetermined information, the plurality of sub-patterns being disposed on either one or both a first main surface side and a second main surface side of the substrate.
