PURPOSE:To obtain a rare earth element-iron type permanent magnet alloy having high magnetic flux density and high coercive force even in the form of a bulk material formed by a sintering method by which a material is easily worked into a desired shape by providing a specified composition. CONSTITUTION:This rare earth element-iron type permanent magnet alloy has a composition represented by the formula, wherein alpha, beta and gamma are atomic ratio, R is at least one kind of element selected among Y and rare earth elements, X is one or more among B, C, N, O, P, H, S, Al and Si, M is one or more among Ag, Pt, Pd, Rh, Re, Ge and Ru, 0.001<=alpha<=0.5, 0.5<=beta<=0.95, 0.001<=gamma<=0.1, and alpha+beta+gamma<1. |
