PROBLEM TO BE SOLVED: To provide a block copolymerized polyamide resin which has a higher crystallization rate than a conventional copolymerized polyamide resin without changing a copolymerization composition ratio.SOLUTION: There is provided a block copolymerized polyamide resin comprising a dicarboxylic acid component and a diamine component, wherein the dicarboxylic acid component comprises an oxalic acid compound and the diamine component comprises two or more diamines. There is also provided a method for producing a polyamide resin comprising a dicarboxylic acid component and a diamine component, wherein the dicarboxylic acid component comprises an oxalic acid compound and the diamine component comprises two or more diamines, wherein, of the two or more diamines, at least one diamine is first added into the dicarboxylic acid component and, thereafter, a diamine comprising a diamine different from the one added first is added. |
