PROBLEM TO BE SOLVED: To provide a method for manufacturing an intermetallic compound target having high transverse rupture strength and composed of an Ru-Al intermetallic compound of B2 superlattice, the target produced by the manufacturing method, and a magnetic recording medium. SOLUTION: In the method for manufacturing the Ru-Al intermetallic compound target, a reaction sintering method is used and metal Ru powder and metal Al powder are formed into an Ru-Al intermetallic compound composed essentially of B2 superlattice and then powder of the Ru-Al intermetallic compound prepared by pulverizing the intermetallic compound is sintered. The Ru-Al intermetallic compound target is constituted of a sintered compact which is produced by the manufacturing method and composed of the Ru-Al intermetallic compound powder composed essentially of B2 superlattice. In the magnetic recording medium, a film of the Ru-Al intermetallic compound composed essentially of B2 superlattice which is deposited using the above Ru-Al intermetallic compound target is used as at least one layer of a base film which is formed between a Co-based magnetic film and a nonmagnetic substrate.
