Claim:
1. A light-emitting device, comprising: a light-emitting element that emits a light with a peak wavelength of not more than 480 nm; a phosphor layer that is operable to convert a wavelength of the light emitted from the light-emitting element; and a heat dissipating member that dissipates heat generated in the phosphor layer, wherein the phosphor layer comprises a layer comprising a single crystal phosphor, a ceramic phosphor, a glass including a phosphor particle, a layer comprising a transparent substrate and a phosphor particle-including resin layer formed thereon, wherein the phosphor layer comprises a layer covering upper and lateral sides of the light-emitting element and being directly connected to the heat dissipating member, or a layer covering the upper side of the light-emitting element and being connected via an adhesive layer to a sidewall surrounding the light-emitting element, wherein the sidewall comprises a first sidewall or a second sidewall, wherein the first sidewall comprises an insulating base surrounding the LED element and a metal layer that is formed on a side surface at the LED side of the base and is in contact with the heat dissipating member and the adhesive layer, wherein the second sidewall comprises a ceramic or a metal in contact with the heat dissipating member and the adhesive layer, and wherein the adhesive layer comprises a resin layer comprising a resin and a particle having a higher thermal conductivity than the resin, or a layer comprising a solder.
