An organic-inorganic composite that has a high metal content, can be easily prepared, and functions as an insoluble solid catalyst excellent in repeated durability with respect to coupling reactions of aryl halides. A polymer (P A ) of a polymerizable composition (A) containing a polymerizable compound (a) having an amino group and a vinyl group and a metal nanoparticle, the polymerizable compound ( a) is (1) a dendrimer (a1) having a tertiary amino group and a reactive functional group (Q 1 ), or a polyethyleneimine (a2) having a reactive functional group (Q 1 ), and (2) the reaction Organic-inorganic composite, characterized in that it is a compound obtained by reacting a reactive functional group (Q 2 ) capable of reacting with a functional functional group (Q 1 ) and a compound (a3) having a vinyl group .
