Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyester resin for blend capable of providing a polyester blended substance having a moderate crystallization rate and preferably applicable to molding of a heat-resistant container or the like by blending it in a polyester resin having a small crystallization rate. SOLUTION: This polyester resin is produced by a method comprising: preparing by a liquid-phase polymerization or a solid-phase polymerization, a polyester resin having an intrinsic viscosity in a range of 0.80 to 1.0 dL/g; and lowering the intrinsic viscosity of the polyester resin to 0.3 to 0.75 dL/g, to prepare a polyester resin having a terminal carboxy group concentration in a range of 20 to 50 eq/ton.
