Abstract
The present invention related to a nitride phosphor represented by the following general formula (1), the nitride phosphor having an x value of less than 0.43 in luminescent color coordinates (x, y) upon being excited with excitation light of 455 nm, and a reflectance Ra of 89% or more at 770 nm;SiN:Z  (1),wherein Ln is a rare-earth element excluding the element used as an activator, Z is an activator, x satisfies 2.7≦x≦3.3, y satisfies 5.4≦y≦6.6, and n satisfies 10≦n≦12.
