In one embodiment of the range-finding sensor of the invention, a light-emitting element that projects light to a range-finding subject, and a light-receiving element that receives reflected light reflected by the range-finding subject, are disposed on a reference face, and the light-emitting element and the light-receiving element are each individually sealed with resin by a translucent resin sealing portion. Further, the outer circumference of the translucent resin sealing portion is covered by an opaque resin sealing portion, and the opaque resin sealing portion is provided with a light-emitting portion slit that constricts the luminous flux of light projected to the range-finding subject, and a light-receiving portion slit that constricts the luminous flux of reflected light reflected by the range-finding subject.
