Abstract: A method of manufacturing a light emitting device includes providing a substrate on which a light source is disposed. An underfill material is ejected from a nozzle onto the substrate substantially around the light source in a circular shape, a shape of a letter ‘C’, or a rectangular shape. A covering member having a recess portion is provided above the light source.

Abstract: A light emitting device includes a substrate, a light source, and a covering member. The light source has an optical axis, a light source bottom portion and a light source upper portion opposite to the light source bottom portion in the optical axis. The light source is provided on the substrate at the light source bottom portion. The covering member has a bottom surface and a top portion opposite to the bottom surface in the optical axis and is provided on the substrate at the bottom surface to cover the light source. The covering member has a recess portion on the top portion above the light source and around the optical axis.
