Abstract

A light emitting device includes a plurality of leads and a board having a first surface on a first surface side thereof and a second surface on a second surface side thereof, the second surface being an opposite side to the first surface. Light emitting elements are mounted on a first surface of a board. A wavelength conversion member is formed unitarily with a transparent member and covers the light emitting elements. The wavelength conversion member has a first end and a second end. The wavelength conversion member is disposed at a first surface side and a second surface side and is elongated in a longitudinal direction when viewed in a plan view of the first surface side of the board. A first metal plate protrudes at the first end of the wavelength conversion member. A second metal plate protrudes at the second end of the wavelength conversion member.
