A polymer compound comprising a residue of a compound of the following formula (1): (wherein, a ring C1, ring C2 and ring C3 represent each independently an aromatic hydrocarbon ring or hetero ring. A1 represents a di-valent group containing one or more atoms selected from a boron atom, carbon atom, nitrogen atom, oxygen atom, phosphorus atom, sulfur atom and selenium atom. R1 represents an alkyl group, alkoxy group, alkylthio group, aryl group, aryloxy group, arylthio group, arylalkyl group, arylalkyloxy group, arylalkylthio group, alkenyl group, alkynyl group, di-substituted amino group, tri-substituted silyl group, acyl group, acyloxy group, imine residue, amide group, acid imide group, mono-valent heterocyclic group, substituted carboxyl group, heteroaryloxy group or heteroarylthio group, or is connected to an atom adjacent to an atom on the ring C3 to which R1 is connected, to form a ring.).
