A phosphor with a high light-emitting intensity, indicated by general formula Me a Re b Si c Al d N e O f . 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. When a=1-x, b=x, c=(2+2p)x(1-y), d=(2+2p)xy, e=(1+4p)x(1-z), and f=(1+4p)xz, parameters p, x, y, and z fulfill the following: 1.610<p<1.620, 0.005<x<0.300, 0.190<y<0.260, and 0.060<z<0.120. A light-emitting device with high luminance is provided by using this phosphor. |
