PROBLEM TO BE SOLVED: To provide a light emitting device capable of improving light extraction efficiency and an illumination device including the light emitting device.SOLUTION: A base plate 2 has a non-forming area 6 in which a copper foil 15 is not formed on the back side 2b, and a white resist layer 16 is formed covering the same. Therefore, even when a beam of light enters into the base plate 2, the light is not absorbed by the copper foil 15 but is reflected to the surface side 2a of the base plate 2. Thus, the light extraction efficiency is improved. 【課題】光取出し効率を向上させることができる発光装置及びこの発光装置を具備する照明装置を提供する。【解決手段】基板２の裏面側２ｂに銅箔１５を形成しない非形成領域６を形成し、これを覆うように白色レジスト層１６を形成しているので、基板２内に光が入射しても銅箔１５で光が吸収されることなく、基板２の表面側２ａに反射することができるので、光取出し効率を向上することができる。【選択図】図４
