Abstract: A light-emitting device includes first and second light-emitting elements arranged along a first direction; at least one light-transmissive member having a lateral surface and covering the upper surfaces of the first and second light-emitting elements; and a light-reflective member in contact with at least portions of the lateral surfaces of the first and second light-emitting elements, and the lateral surface of the light-transmissive member. The light-transmissive member has first and second surfaces exposed from the light-reflective member and located above the upper surfaces of the first and second light-emitting elements, respectively. The light-reflective member includes a first portion located between the first surface and the second surface in the first direction above the first and second surfaces. The first portion includes at least one concave curved surface in a first cross-section extending along the first direction and perpendicular to the upper surface of the first light-emitting element.
