An object of the present invention is to provide a polycyclic fused ring polymer which has a structure capable of showing high charge transport properties and also is excellent in solubility into a solvent. The polycyclic fused ring 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:
wherein 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.
