摘要： A surface-emitting laser array includes a plurality of surface-emitting laser elements, a plurality of optical elements, and a light shielding member. The plurality of surface-emitting laser elements are arranged on a first surface of a substrate and configured to emit light in a direction crossing the first surface. The plurality of optical elements are arranged on a second surface opposite to the first surface of the substrate to correspond to the surface-emitting laser elements and configured to change a radiation angle of the light. The light shielding member is arranged in a region between the optical elements on the second surface of the substrate.
