PROBLEM TO BE SOLVED : To provide a method for producing nanoparticles of rare earth alloy by laser abrasion by preventing oxidation of the nanoparticles. SOLUTION : In the method for producing the nanoparticles of rare earth alloy by laser abrasion, a laser beam-transmissive liquid 18 which does not oxidize the nanoparticles of rare earth alloy and a target 20 of rare earth alloy at least partially immersed into the liquid are arranged in an air tight container 12 and in a gas atmosphere which does not oxidize the nanoparticles of rare earth alloy, the part immersed into the liquid, of the target is irradiated with laser beam 24, and the nanoparticles of rare earth alloy are released from the target into the liquid.
