摘要：PROBLEM TO BE SOLVED: To provide a novel polymerization catalyst which yields a polyester excellent in transparency. SOLUTION: The polymerization catalyst for the polyester contains at least one chosen from aluminum and an aluminum compound as a metal-containing component and at least one phosphorous compound of the formula: (R<SP>1</SP>)n-A-C(R<SP>2</SP>)(R<SP>3</SP>)-(P=O)(OR<SP>4</SP>)(OR<SP>5</SP>) (wherein n is 0-10; A is a 6-50C aromatic ring structure or a 4-50C heterocyclic structure; R<SP>1</SP>is a 1-20C hydrocarbon group, a 1-20C alkoxy group or a halogen group; R<SP>2</SP>and R<SP>3</SP>are each independently a hydrogen atom, a 1-20C hydrocarbon group or a 1-20C alkoxy group, provided that both R<SP>2</SP>and R<SP>3</SP>are not hydrogen atoms at the same time; and R<SP>4</SP>and R<SP>5</SP>are each independently a hydrogen atom, a 1-20C hydrocarbon group or a 1-20C hydrocarbon group containing a hydroxy group or an alkoxy group).
