Abstract:
A light-emitting module includes: a first light-emitting element that emits light from an upper surface and side surfaces thereof; a second light-emitting element that mainly emits light from an upper surface thereof; a first sealer; and a second sealer. A first ratio, defined as a ratio of a heightwise distance from a top of the first sealer to the upper surface of the substrate with respect to a width of the first sealer at the upper surface of the substrate, is larger than a second ratio, defined as a ratio of a heightwise distance from a top of the second sealer to the upper surface of the second light-emitting element with respect to a width of the second sealer at a position corresponding to the upper surface of the second light-emitting element. A ratio of the first ratio to the second ratio is less than 1.85.
