Zusammenfassung:	Provided is a phosphor represented by a composition of the following formula (1), (Sr a ,Ba b ,Ca c ,Eu x ,M 1 d ,M 2 e )SiO f ·gMgO ···formula (1) (here, M 1 represents at least one group 3 element selected from Lu and Sc, M 2 represents an alkali metal element selected from Li, Na, and K, and 0 < a ¤ 2, 0 < b ¤ 2, 0 ¤ c ¤ 2, 0.0015 ¤ d ¤ 0.045, 0 ¤ e ¤ 0.06, 0 < x ¤ 0.1, 3.7 ¤ f ¤ 4.1, and 0 ¤ g ¤ 1 are satisfied). In addition, provided is a light-emitting device including the phosphor and a light source for irradiating the phosphor with excitation light to cause the phosphor to emit light.
