PROBLEM TO BE SOLVED : To provide : a method for producing a magnet without using dysprosium, capable of acquiring high residual magnetic flux density and high transverse intensity without using a bond; and a magnet. SOLUTION : A method for producing a magnet includes : an oxide film bonding step of forming a compact 200 by using raw material powder 10, 30 of an R-Fe-N based compound containing a rare earth element as R, or raw material powder 10, 30 of an Fe-N based compound, and bonding the raw material powder 10, 30 with each other by an oxide film 32 formed on the surface of the raw material powder 10, 30; and a coating step of surrounding the surface of the compact 200 with a coating film 40.
