Disclosed is an aromatic polymer containing one or more repeating units represented by the following formula (1). (In the formula, Ar1 represents an arylene group having a fused ring structure or a divalent heterocyclic compound group having a pi-conjugated system, and contains a group represented by the formula (2) below. This group is bonded to a carbon atom having a sp2 hybrid orbital which is contained in a ring of the ring structure of the arylene group having a fused ring structure or the divalent heterocyclic compound group having a pi-conjugated system represented by Ar1. (In the formula (2), E1 represents a hydrogen atom, a halogen atom or a monovalent organic group; Ar2 represents a group having a divalent pi-conjugated cyclic compound residue, and two Ar2's may be the same as or different from each other; X1 represents a divalent group selected from the group consisting of -NQ1-, -PQ2- and -BQ3-, and Q1-Q3 independently represent a substituent; Z represents a direct bond or a divalent linking group, and two Z's may be the same as or different from each other; mi's respectively represent 0 or 1; and in case where two X1's exist, they may be the same as or different from each other.)
