A method for manufacturing a light emitting device includes forming a multilayer body including a light emitting layer so that a first surface thereof is adjacent to a first surface side of a translucent substrate. A dielectric film on a second surface side opposite to the first surface of the multilayer body is formed having first and second openings on a p-side electrode and an n-side electrode. A seed metal on the dielectric film and an exposed surface of the first and second openings form a p-side metal interconnect layer and an n-side metal interconnect layer separating the seed metal into a p-side seed metal and an n-side seed metal by removing a part of the seed metal. A resin is formed in a space from which the seed metal is removed.
