Abstract: A method of manufacturing a light emitting device, includes providing a light emitting element having an element upper surface, an element lower surface opposite to the element upper surface in a thickness direction of the light emitting element, and an element side surface between the element upper surface and the element lower surface. A wavelength converter having a converter lower surface is provided. The wavelength converter is joined to the light emitting element using an adhesive so that the converter lower surface faces the element upper surface. The converter lower surface has an exposed region that does not face the element upper surface viewed along the thickness direction. The adhesive covers the element side surface and the exposed region.
