<p>PROBLEM TO BE SOLVED: To provide an optical device capable of achieving an improvement in manufacturing efficiency.SOLUTION: The optical device includes a light-emitting element 11, a light-receiving element 12, a light-emitting side light-shielding resin part 6 covering the light-emitting element 11, and a light-receiving side light-shielding resin part 7 covering the light-receiving element 12. A light exit hole 689 for emitting light emitted from the light-emitting element 11 is formed in the light-emitting side light-shielding resin part 6. A light incident hole 789 through which light is incident on the light-receiving element 12 is formed in the light-receiving side light-shielding resin part 7. The light exit hole 689 faces the light incident hole 789. The light-emitting side light-shielding resin part 6 is joined to the light-receiving side light-shielding resin part 7.</p> |
