Provided is a solid polymer electrolyte having increased heat resistance and high proton conductivity and a proton conductive membrane composed of the electrolyte. Also provided is a copolymer having a sulfonic acid group. The copolymer includes a repeating unit represented by Formula (1): (see formula 1) (in the formula, Y denotes at least one kind of structure selected from the group consisting of -CO-, -SO2-, -SO-, -CONH-, -COO-, -(CF2)1- (1 is an integer of 1 to 10), and -(CF3)2-; W denotes at least one kind of structure selected from the group consisting of a direct bond, -CO-, -SO2-, -SO-, -CONH-, -COO-, -(CF2)1- (1 is an integer of 1 to 10), -C(CF3)2-, -O-, and -S-; Z denotes a direct bond or at least one kind of structure selected from the group consisting of -(CH2)1- (1 is an integer of 1 to 10), -C(CH3)2-, -O-, -S-, -CO-, and -SO2-; R30 denotes a nitrogen-containing aromatic ring having a substituent represented by -SO3H, -O(CH2)h SO3H, or -O(CF2)h SO3H (h is an integer of 1 to 12); p is an integer of 0 to 10; q is an integer of 0 to 10; r is an integer of 1 to 5; and k is an integer of 0 to 4).
