Provided are a transparent phosphor made without a resin or a low-melting-point glass that easily deteriorates and having a fine color rendering property, and a method of manufacturing the same. The transparent phosphor which provides white fluorescent light upon incidence of excitation light is characterized in that it is composed of two or more kinds of fluorescent phases, the fluorescent phases have a main phase made of an amorphous phase composed mainly of A (A being any one or more elements of Al, Ga, Ge, W, P, V, Zn, Si, B, Mg, Ca, Ba, Sr, and Sc), Ln (Ln being any one or more elements of Y, Gd, La, Sm, Dy, Ho, Er, Yb, and Lu), O, and R as an activator (R being any one or more elements of Eu, Tb, Ce, Sm, Tm, Pr, Nd, Dy, Ho, Er, Yb, Mn, Ti, Fe, Cr, and Pb that is/are other than an element or elements selected as Ln), and the fluorescent phases are different at least in the kind of R or the average valence of R.
