The phosphor according to the present invention has M (py) Al (2q + rx) Si x which emits light having a center wavelength in the wavelength region of 350 nm to 480 nm as the excitation source and a light having the center wavelength of the wavelength region of 490 nm to 550 nm. Phosphors represented by O (p + 3q-3x / 2) N (r + 4x / 3) Eu y . (In the above formula, M is at least one alkaline earth metal ion selected from the group consisting of Ba, Sr, Ca, Mg and Be, 1≤p≤3, 1≤q≤3, 0≤r≤1, 0 ≤ x ≤ 6, and 0.001 <y ≤ 0.4.) |
