PROBLEM TO BE SOLVED: To provide an optical range-finding sensor that can prevent positional deviations between constituent members due to expansion upon heating and contraction upon cooling, and thereby prevent fluctuations in range-finding characteristics.SOLUTION: An optical range-finding sensor has a structure in which two flanks 15B and 15C of a metal-made lens plate 15 hold between them two side faces 7B and 7C of a first light intercepting mold resin part 7, and this structure can prevent the metal-made lens plate 15 from deviating in position in the direction of crossing the array direction of a light emitting side lens 16 and a light receiving side lens 18 relative to the first light intercepting mold resin part 7. A second light intercepting mold resin part 21 covers the two flanks 15B and 15C of the metal-made lens plate 15 and can thereby prevent the metal-made lens plate 15 from deviating in position in the direction of crossing the array direction relative to the first light intercepting mold resin part 7. |
