The present invention relates to a phosphor and, particularly to a nitride phosphor, a manufacturing method therefor, and a light emitting device package using the same. The present invention may provide a nitride phosphor which is represented by chemical formula 1 and has an orthorhombic crystalline structure in which lattice constants are respectively a = 10.2666 Å, b = 10.3084 Å, c = 14.5643 Å, and a crystalline angle is α = β = γ = 90° <Chemical formula 1> M(1-x)uSivNw: Rx (0.5 < u < 1.5, 0.5 < v < 1.5, 1.7 < w < 2.3) (In the chemical formula, M is one or more elements selected from alkaline earth metal Mg, Ca, Sr, and Ba; R, as an activator, is one or more elements selected from Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Er and Yb.) |
