Zusammenfassung:	There is provided a fluorescent material having a composition represented by the following Formula (1). (Sr a ,Ba b ,Eu x ,M 1 d ,M 2 e ) SiO f ·cMgO ... Formula (1) (In the formula, M 1 is at least one tertiary group element selected from Y and Tb; M 2 is an alkali metal selected from Li, Na, and K; and 0 < a < 2, 0 < b < 2, 0 ¤ c < 1, 0.001 ¤ d ¤ 0.06, 0 ¤ e ¤ 0.06, 0 < x < 0.1, and 3.7 ¤ f ¤ 4.1 are set.) Further, there is provided a light-emitting device including: the fluorescent material; and a light source irradiating the fluorescent material with excitation light to cause the fluorescent material to emit light.
