According to the present invention, a substrate 11 , a cluster of LED chips, which are arranged two-dimensionally on the substrate 11 , and a plurality of phosphor resin portions 13 a, 13 b that cover the respective LED chips are provided. The phosphor resin portion 13 a, 13 b includes a phosphor for transforming the emission of its associated LED chip into a light ray having a longer wavelength than that of the emission. A size of the phosphor resin portions 13 b, which cover the LED chips located in an outer region of the cluster, is set bigger than that of the other phosphor resin portions 13 a, which cover the LED chips located in the remaining non-outer region.
