description Disclosed are: a water-insoluble copolymer having a constituent unit (X) derived from a hydroxycarboxylic acid and a constituent unit (Y) derived from an amino group-containing polyvalent carboxylic acid, wherein the molar ratio between the constituent units, namely (X)/(Y) satisfies 2/1 = (X)/(Y) < 8/1 and the amide bond ratio of the constituent unit (Y) represented by formula (1) is within the ranges of formulae (2-1)-(2-3); a method for producing this copolymer; and a resin composition which contains this copolymer. Amide bond ratio (%) = A/Asp × 100 (1) (A = number of moles of amide bonds in constituent unit (Y), Asp = number of moles of constituent unit (Y)) (If 2/1 = (X)/(Y) < 4/1) Amide bond ratio (%) > 25 (2-1) (If 4/1 = (X)/(Y) = 6.5/1) Amide bond ratio (%) > 30 (2-2) (If 6.5/1 < (X)/(Y) < 8/1) Amide bond ratio (%) > 50 (2-3). Se describen un copolímero hidroinsoluble que tiene una unidad constitucional (X) derivada a partir de un ácido hidroxicarboxílico y una unidad constitucional (Y) derivada a partir de un ácido carboxílico polivalente que contiene un grupo amino, en donde la proporción molar (X/Y) de unidades constitucionales es de 2/1 = (X/Y) < 8/1, y la proporción de enlace amídico de la unidad constitucional (Y) representada por la siguiente fórmula (1) se define mediante las siguientes fórmulas (2-1) a (2-3); y un método de producción del mismo, y una composición de resina que contiene tal copolímero. Proporción de enlace amídico (%) = A/Asp x 100 (1) [A = cantidad de moles de un enlace amídico en (Y), Asp = cantidad de moles de (Y)] [cuando 2/1 = (X/Y) < 4/1] proporción de enlace amídico (%) = 25 (2-1) [cuando 4/1 = (X/Y) = 6.5/1] proporción de enlace amídico (%) = 30 (2-2) [cuando 6.5/1 < (X/Y) < 8/1] proporción de enlace amídico (%) = 50 (2-3).
