A gas detection apparatus 1 includes a light emitting element 3 provided on a main surface 20 of the substrate 2 for emitting light from a light emitting surface 31; a light receiving element 4 provided on the main surface 20 of the substrate 2 for receiving the light on a light receiving surface 41; and a light guide member 5 for guiding the light emitted by the light emitting element 3 to the light receiving element 4. In plan view of the main surface of the substrate, the light emitting surface 31 and the light receiving surface 41 are shaped to have corners, and side of the light emitting surface 31 after being subjected to a magnification or reduction and a translation do not overlap sides of the light receiving surface 41.
