The invention addresses a problem of obtaining a conjugated polymer having a higher molecular weight through coupling reaction of monomers using a transition metal catalyst. The invention relates to a method for producing a conjugated polymer, which comprises polymerizing one or more monomers through a coupling reaction, wherein the coupling reaction of the monomer is carried out by using one or more kinds of homogeneous transition metal complex catalysts and one or more kinds of heterogeneous transition metal complex catalysts in combination.
