Abstract
A light emitting device includes at least one semiconductor light emitting element, and a wavelength conversion layer which is formed on a surface of the semiconductor light emitting element and which includes a resin layer containing a wavelength conversion member for converting a wavelength of light emitted from the semiconductor light emitting element. The wavelength conversion layer covers an upper surface or the upper surface and a side surface of the semiconductor light emitting element. A content of an inorganic material including the wavelength conversion member, or a content of an inorganic material including the wavelength conversion member and an inorganic filler, in the resin layer is 30% by mass or more and 99% by mass or less.
