To provide a phosphor containing a comparatively much red component and having high light emitting efficiency, high brightness and further high durability, the nitride phosphor is represented by the general formula L<SUB>X</SUB>M<SUB>Y</SUB>N<SUB>((2/3)X+(4/3)Y)</SUB>:R or L<SUB>X</SUB>M<SUB>Y</SUB>O<SUB>Z</SUB>N<SUB>((2/3)X+(4/3)Y-(2/3)Z)</SUB>:R (wherein L is at least one or more selected from the Group II Elements consisting of Mg, Ca, Sr, Ba and Zn, M is at least one or more selected from the Group IV Elements in which Si is essential among C, Si and Ge, and R is at least one or more selected from the rare earth elements in which Eu is essential among Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and Lu.); contains the another elements.
