Abstract: A light emitting device includes: a light-emitting element; a resin package including a plurality of leads including first and second leads, a first resin portion, a second resin portion extending around an element mounting region, and a third resin portion, wherein the plurality of leads and the first resin portion define a recess having an inner side-wall surface; a light-reflective member being located between the inner side-wall surface and the second resin portion inside the recess; and an encapsulant located in a region of the recess that is surrounded by the light-reflective member, the encapsulant covering the second resin portion and the light-emitting element. The second resin portion has a depression in a surface thereof. A part of the encapsulant is located inside the depression of the second resin portion.
