Disclosed is a solid polymer electrolyte which has excellent proton conductivity, while being improved in heat resistance. Also disclosed is a proton conducting membrane which is composed of such a solid polymer electrolyte. Specifically disclosed is a copolymer having a sulfonic acid group, which is characterized by containing a repeating unit represented by the following general formula (1). [chemical formula 1] (1) (In the formula, Y represents at least one structure selected from the group consisting of -CO-, -SO2-, -SO-, -CONH-, -COO-, -(CF2)l- (wherein l represents an integer of1-10) and -C(CF3)2-; W represents at least one structure selected from the group consisting of a direct bond, -CO-, -SO2-, -SO-, -CONH-, -COO-, -(CF2)l- (wherein l represents an integer of 1-10), -C(CF3)2-, -O- and -S-; Z represents a direct bond or at least one structure selected from the group consisting of -(CH2)l- (wherein l represents an integer of 1-10), -C(CH3)2-, -O-, -S-, -CO- and -SO2-; R represents a nitrogen-containin
