The present invention provides a phosphor emitting green fluorescence when being effectively excited by excitation light in a wavelength range from blue light to near-ultraviolet light, having an emission intensity that does not vary significantly with variation in the wavelength of the excitation light, and being manufactured easily. The phosphor includes a chemical structure represented by the following general formula (A): A(M 1-a-x Eu a Mn x )L(Si 1-b Ge b ) 2 O7, ··· (A), where A is one or more elements selected from Li, Na, and K, M is one or more elements selected from Mg, Ca, Sr, Ba, and Zn, L is one or more elements selected from Ga, Al, Sc, Y, La, Gd, and Lu, a is a numerical value satisfying 0.001‰¤a‰¤0.3, b is a numerical value satisfying 0‰¤b‰¤0.5, and x is a numerical value satisfying 0‰¤x‰¤0.2. |
