PROBLEM TO BE SOLVED: To provide the packaging structure of an optical distance measuring apparatus for positioning elements in omnidirections. SOLUTION: The optical distance measuring apparatus comprises a light projection section 2; a light reception section 3; and a main board for assembling them, thus measuring distance in the direction of the light axis of a target. The light projection section 2 comprises a lens for focusing luminous flux in the direction of the light axis; a retaining frame 22 for retaining the lens for mounting on the main board; and a sub board 26 that mounts a light emitting element 23 for radiating the luminous flux and is mounted on the retaining frame 22 while opposing the lens. In the sub frame 26, a through hole 28 for adjustment is formed. In the retaining frame 26, a recess 27 for adjustment having large opening dimensions is formed at a site corresponding to the through hole 28. A thin rod 70 is inserted into the recess 27 through the through hole 28, and the position of the sub board 26 is adjusted with the thin rod 70 as a lever by setting a part where the tip and the bottom of the recess 27 come into contact to be a support.
