PROBLEM TO BE SOLVED : To provide an R-T-B-base alloy in which concentration of Dy is high, whose pulverization property is not reduced as well, and which is made into the raw material of a rare earth permanent magnet having excellent magnetic properties. SOLUTION : Disclosed is the R-T-B-base alloy that is a raw material to be used for the rare earth permanent magnet. In the R-T-B-base alloy, R contains not less than 20% by mass of Dy, and diffraction peaks appear at 31.1 to 31.3° and 37.8 to 38.0° as measured by X-ray diffractometry (2[!theta!]/[!theta!]) using CuKα.
