A phosphor indicated by general formula MeaRebSicAldNeOf. In the formula: Me has Sr as an essential element thereof and can include one or more types of element selected from Na, Li, Mg, Ca, Ba, Sc, Y, and La; and Re has Eu as an essential element thereof and can include one or more types of element selected from Mn, Ce, Tb, Yb, and Sm. In addition, when a=1−x, b=x, c=(2+2p)×(1−y), d=(2+2p)×y, e=(1+4p)×(1−z), and f=(1+4p)×z, parameters p, x, y, and z fulfill the following: 1.620<p<1.635, 0.005<x<0.300, 0.200<y<0.250, and 0.070<z<0.110. A light-emitting device with high luminance is provided by using this phosphor.
