Provided are transparent fluorescent sialon ceramics having fluorescence and light transmittance, and a method for manufacturing the same. Such transparent fluorescent sialon ceramics have the general formula M x (Si,Al) y (N, O) z (provided that M is at least one selected from the group consisting of silver, Li, alkaline earth metals and rare earth metals, 0 ≤ x It consists of a mother body which consists of a silicon nitride type compound represented by /z<3, 0<y/z<1), and a sialon phosphor containing a luminescence center element. |
