Abstract: A light emitting device includes a base member; a light emitting element mounted on the base member; a light-transmissive member that covers an upper surface of the light emitting element, and is substantially rectangular in a plan view; and a light reflecting member that covers a lateral surface of the light-transmissive member, the light reflecting member having a substantially rectangular frame shape in a plan view. A width of the light reflecting member is smaller along a short side of the light-transmissive member than along a long side of the light-transmissive member. A height of the light reflecting member is smaller along the short side of the light-transmissive member than along the long side of the light-transmissive member at a position separated from an outer edge of the light reflecting member by a predetermined distance.
