PROBLEM TO BE SOLVED : To provide a nitride phosphor in which brightness, internal quantum efficiency, and external quantum efficiency are more improved than those of a conventional product. SOLUTION : The nitride phosphor is represented by the following general formula (1) : LnxSiyNn : Z, and is characterized in that 25% or more of all water adsorbed inside the nitride phosphor is desorbed between 170°C and 300°C in a thermogravimetry. In the general formula (1), Ln is a rare earth element excluding elements used as activators, Z is an activator, x satisfies 2.7≤x≤3.3, y satisfies 5.4≤y≤6.6, and n satisfies 10≤n≤12.
