    摘要: Provided is a light emitting device which is suitable for a lighting apparatus, such as a projector, requiring high brightness and high light intensity exhibits little change in light emission colour and a low reduction in light emission intensity during usage, and uses a remote phosphor. According to one embodiment of the present invention, the light emitting device (10) has: an LED element (12); a side wall (13) which surrounds the LED element (12); a phosphor layer (15) which is fixed to the side wall (13) with an adhesive layer (14) therebetween, and is positioned above the LED element (12); and a metal pad (11) as a heat dissipating member. The side wall (13) has: an insulating base (13b) which surrounds the LED element (12); and a metal layer (13a) which is formed on a side surface at the LED element (12) side of the base (13b), and is in contact with the metal pad (11) and the adhesive layer (14). The adhesive layer (14) is: a resin layer that comprises a resin containing particles which have higher thermal conductivity than the resin; or a layer that comprises solder.
