Abstract:
This optical device (30) is provided with a light-emitting device (10) and a sensor device (20) (light-receiving element (220)). The light-emitting device (10) is provided with a substrate (100), a plurality of light-emitting units (140), and a light transmissive unit (106). The light-emitting units (140) are located on a first surface (100a) side of the substrate (100). The light-emitting units (140) have a light shielding unit (102: first light shielding unit). The light shielding unit (102) is located at a position at which light is shielded which is emitted from the light-emitting device (10) at at least any angle between 70° and 90° on the first surface (100a) side among light emitted by a light-emitting unit (140: first light-emitting unit) adjacent thereto.
