In order to provide a phosphor containing a relatively large amount of reddish components, high luminous efficiency and brightness, and high durability and a manufacturing method thereof, the general formula L X M Y N ((2/3) X + (4/3) Y) : R or L X M Y O Z N ((2/3) X + (4/3) Y- (2/3) Z) : R (L is Mg, Ca, Sr, Ba, Zn At least one or more selected from Group II elements, M is at least one or more selected from Group IV elements essential for Si among C, Si, and Ge, and R is Y, La, Ce, Pr, Nd, Sm, At least a portion of light having a first emission spectrum having a peak wavelength of 500 nm or less, and at least one of at least one selected from rare earth elements of Eu, Gd, Tb, Dy, Ho, Er, and Lu; A nitride phosphor (base nitride phosphor) that absorbs and emits light having a second emission spectrum having at least one or more peaks in the range of 520 to 780 nm, and further includes other elements. |
