[PROBLEMS] To provide a more practical polymer-supported metal complex catalyst that has a simple structure, can be easily produced at low cost, and has excellent recovery and reusability, and a catalyst ligand suitable for the preparation of the catalyst. Offer. Styrene monomer (1a): 25 to 90 mol%, p-phosphine group-containing styrene (2a): 1 to 70 mol%, divinylbenzene (3a): 1 to 30 mol% (provided that all monomers are included) ((1a) + (2a) + (3a)) = 100 mol%) and a phosphorus-containing styrenic copolymer (A), and the formula (B): “MX q L r ” (M is a transition metal atom such as Pd or its ion, X is a halogen ion, L is a ligand such as triphenylphosphine, and q and r are integers of 0 or more) A polymer-supported transition metal complex in which the transition metal atom or transition metal ion M in the complex (C) is 0.1 to 20% by weight in the complex (C).
