To provide a phosphor having an emission spectrum with a broad peak in a range of blue color (peak wavelength range from 400 nm to 500 nm) and a broad and flat excitation band in a range of near ultraviolet/ultraviolet, and having an excellent emission efficiency and emission intensity/luminance, a manufacturing method of the same, and a light emitting device using the phosphor. The phosphor is provided, which is given as a general composition formula expressed by MmAaBbOoNn:Z, (where element M is the element having bivalent valency, element A is the element having tervalent valency, element B is the element having tetravalent valency, O is oxygen, N is nitrogen, and element Z is more than one kind of element acting as an activator.), satisfying 5.0<(a+b)/m<9.0, 0≦a/m≦2.0, 0≦o<n, and n=2/3m+a+4/3b−2/3o, and having an emission spectrum with a maximum peak wavelength from 400 nm to 500 nm under an excitation of the light in a wavelength range from 350 nm to 430 nm. |
