摘要：
A thermoplastic polyester resin represented by general formula (1) or (2) which has a melt index of from 1 to 50. The polyester resin is excellent in flexibility, flame retardancy, and thermal aging resistance. The electric wire, insulated cable, and heat-shrinkable tube obtained with the resin are excellent also in abrasion resistance: ##STR1## whereinRa1 is an aromatic and/or aliphatic hydrocarbon group;Ra2 is a hydrocarbon group;Ra3 is an aliphatic hydrocarbon group having a C.dbd.C bond;Rb is a hydrocarbon group; andl, m, n, p and q each is a positive integer.
