A visible light-absorbing complex includes an electron acceptor and an electron donor, the electron donor having a triazine-based dendritic polymer formed of a core group (C) and branch groups, each of the branch groups being composed of terminal groups (P) and a triazine-based moiety group. The triazine-based dendritic polymer is represented by the following formula (I): wherein G indicates the generation number, "G-1" indicating the layer number of the branch groups, n being the number of the terminal groups, m being the number of the branch groups, wherein Z1 is a divalent group containing O or N, and an atom of Z1 bonding to the triazine group should be O or N; and wherein, when G is 1, the core group should be a triazine-based core group having a triazine ring, and an atom of each of the terminal groups bonding to the triazine ring should be O or N.
