Light emitting device, manufacturing method for light emitting device, and distance measuring device

Manufacturing method (substrate 51, light emitting element 53, structure body 71, first structure body 71a, and second structure body 71b)

• A manufacturing method for a light emitting device, the manufacturing method comprising:
• forming a plurality of light emitting elements on a first surface of a substrate;
• and
• forming, on a second surface of the substrate, a plurality of structure bodies through which light emitted from the plurality of light emitting elements is transmitted, wherein
• at least any of the structure bodies is formed to include a first structure body through which a first portion of the light is transmitted and a second structure body through which a second portion of the light is transmitted, the second structure body having a function different from a function of the first structure body.

Distance measuring device (light emitting device 1, imaging device 2, distance measuring unit 31, substrate 51, light emitting element 53, structure body 71, first structure body 71a, and second structure body 71b)

• A distance measuring device comprising:
• a light emitting device including a plurality of light emitting elements configured to generate light, the light emitting device being configured to irradiate a subject with the light from the light emitting elements;
• an imaging device configured to receive the light reflected by the subject and generate an image signal from the light;
• and
• a distance measuring unit configured to measure a distance to the subject on a basis of the image signal generated by the imaging device, wherein
• the light emitting device includes:
• a substrate;
• the plurality of light emitting elements provided on a first surface of the substrate;
• and
• a plurality of structure bodies through which light emitted from the plurality of light emitting elements is transmitted, the plurality of structure bodies being provided on a second surface of the substrate, and
• at least any of the structure bodies includes a first structure body through which a first portion of the light is transmitted and a second structure body through which a second portion of the light is transmitted, the second structure body having a function different from a function of the first structure body.
