The present invention can provide: a novel fluorescent body having novel light-emission characteristics different from those of a conventional nitride fluorescent body or a conventional oxynitride fluorescent body; a method for manufacturing the same; and a light-emitting device using the same. According to an embodiment of the present invention, the fluorescent body contains at least element A, element D, and element X (where A represents at least one element selected from the group consisting of Mg, Ca, Sr, and Ba, D represents Si element, and X represents at least one element selected from the group consisting of O, N, and F), and optionally contains, as necessary, an inorganic substance that further contains, in a crystal represented by A26(D,E)51X86 containing element E (where E represents at least one element selected from the group consisting of B, Al, Ga, and In), element M (where M represents at least one element selected from the group consisting of Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, and Yb). The fluorescent body optionally has a maximum value of a light-emission peak in a wavelength in a range of 630-850 nm when being irradiated with an excitation source. |
