Provided is a chemically and thermally stable phosphor having different emission characteristics than the conventional phosphor and exhibiting high emission intensity if combined with an LED of 470 nm or less. The phosphor of the present invention is represented by a composition formula: M d A e D f E g X h (d+e+f+g+h = 1; M is one or more kinds of elements selected from Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, and Yb; A is one or more kinds of elements selected from Mg, Ca, Sr, and Ba; D is one or more kinds of elements selected from Si, Ge, Sn, Ti, Zr, and Hf; E is one or more kinds of elements selected from B, Al, Ga, In, Sc, Y, and La; and X is one or more kinds of elements selected from O, N, and F) and parameters d, e, f, g, and h satisfy the predetermined condition. |
