An object of the present invention is to provide a polycyclic fusedring polymer which has a structure capable of showing high charge transport properties and also is excellent in solubility into a solvent. The polycyclic fusedring polymer according to the present invention includes: a plurality of one of a first structural unit represented by the following formula (1) and a second structural unit represented by the following formula (2); or the first structural unit and the second structural unit in combination:n nwherein X 1 and X 2 represent an oxygen atom, a sulfur atom or a selenium atom, and R 1 and R 2 represent a halogen atom, an unsaturated alkyl group, an alkyl group, a non-alkyl group containing an alkyl group, an aryl group, or a monovalent heterocyclic group; R 3 and R 4 represent a monovalent group, and when a plurality of R 3 and R 4 exist, these may be the same or different; and m, n, s and t are an integer of 0 to 2. |
