Abstract
A light emitting device includes a substrate member, a light emitting element, a resin member, an insulating layer and a fluorescent material layer. The light emitting element is arranged on the substrate member. The resin member surrounds sides of the light emitting element, and has a top portion located higher than a light emission surface of the light emitting element. The insulating layer covers the light emission surface of the light emitting element and an outer wall surface and an inner wall surface of the top portion of the resin member. The fluorescent material layer covers a surface of the insulating layer.

A light emitting device comprising:
- a substrate member;
- a light emitting element arranged on the substrate member;
- a resin member surrounding sides of the light emitting element, and having a top portion located higher than a light emission surface of the light emitting element;
- an insulating layer covering the light emission surface of the light emitting element and an outer wall surface and an inner wall surface of the top portion of the resin member, the insulating layer containing aluminum oxide;
- and
- a fluorescent material layer covering a surface of the insulating layer, wherein
- the inner wall surface of the resin member is continuous with the light emission surface of the light emitting element, and
- the outer wall surface of the resin member is continuous with the inner wall surface of the resin member at the top portion.
A light emitting device comprising:
- a substrate member;
- a light emitting element arranged on the substrate member;
