<P>PROBLEM TO BE SOLVED: To provide an optical device that is less prone to false detection. <P>SOLUTION: The optical device comprises a substrate 1, a wiring pattern 8 formed on the substrate 1, a light-receiving element 3 and a light-emitting element 2 arranged, respectively, on the substrate 1 with a space therebetween in the x direction, a translucent resin 4 covering the light-receiving element 3, a translucent resin 5 covering the light-emitting element 2, and a light-shielding resin 6 covering the translucent resin 4 and the translucent resin 5. The wiring pattern 8 includes a first light interruption part 83 interposed between the light-shielding resin 6 and the substrate 1 and located between the light-receiving element 3 and the light-emitting element 2 in the xy plan view, and the first light interruption part 83 traverses the light-emitting element 2 when viewed in the x direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
