Abstract

A light emitting device including a board, light emitting elements, a wavelength conversion member, and first and second metal plates. The board has a first surface and an opposite second surface, and is longer in a first direction than in a second direction perpendicular to the first direction. The light emitting elements are mounted on the first surface and are arrayed in a row along the first direction. The wavelength conversion member includes a first portion covering the light emitting elements and a second portion covering the second surface. The light emitting elements includes a first light emitting element located closest to the first metal plate, and a second light emitting element located closest to the second metal plate. The light emitting elements on the first surface are located between a first end surface of the first metal plate and a first end surface of the second metal plate.
