It is an object of the present invention to provide a method for producing a magnetostrictive element which can give an anisotropic magnetostrictive element from a starting material containing Sm and a transition metal element. The method produces an anisotropic magnetostrictive element by compacting the starting powder in a magnetic field to produce a compact, and sintering the compact to produce a sintered body having a composition of SmFe<SUB>2</SUB>. It is preferable that the starting powder is produced by mixing a first alloy for the main phase of the magnetostrictive element with a second alloy having a lower melting point than the first alloy. It is recommended that the first alloy has a larger particle size than the second alloy.
