Provided is a phosphor for producing a one-chip type white LED illumination or the like in combination with a near-ultraviolet / ultraviolet LED, a blue LED, or the like, and having excellent luminous efficiency including luminance. SOLUTION: General formula MmAaBbOoNn: Z (M element is one or more elements having a valence of II, A element is one or more elements having a valence of III, and B element is IV One or more elements having a valence of valence, O is oxygen, N is nitrogen, and Z element is one or more activators.) a = (1 + x) × m, b = (4-x) × m, o = xx × m, n = (7−x) × m, 0 ≦ x ≦ 1, and has a wavelength range of 300 nm to 500 nm. When excited with light, the peak wavelength in the emission spectrum is in the range of 500 nm to 620 nm. [Selection figure] None |
