Abstract
An optical distance sensor is provided with a substrate on which a light emitting element and a light detecting element are disposed, and a single optical structure including a first converging mechanism for converging a light beam emitted from the light emitting element, a second converging mechanism for converging a light beam reflected by an object at a distance to be measured, and a reflecting mechanism for deflecting the light beam reflected by the object twice.
