Abstract: PROBLEM TO BE SOLVED: To provide a more efficient method for producing a polyoxamide resin that shortens a polymerization cycle in the method for producing the polyoxamide resin.SOLUTION: In the production method for obtaining the polyoxamide resin by the polycondensation reaction of an oxalic acid diester and a diamine, the polymerization cycle is shortened due to the finding that a high molecular weight polyoxamide resin is produced without lowering the temperature in a pressure vessel to not higher than the melting point of the polyoxamide resin by adding 0.1-5.0 mol% excess oxalic acid diester to a diamine at a temperature not lower than the melting point of the polyoxamide resin obtained and mixing them, by performing pressure polymerization in the presence of alcohol produced by the polycondensation reaction, and then by performing melt polymerization at normal pressure and a temperature not lower than the melting point of the polyoxamide resin in the pressure vessel.
