1. A polymer compound including a structural unit represented by formula (V) and a structural unit represented by formula (II): wherein X represents a sulfur atom, an oxygen atom, a selenium atom, —NH— or —N(Ra)—; Ra represents a substituent; Y represents a divalent heterocyclic group represented by formula (Y-1) to (Y-5); Z represents a divalent group represented by (Z-1) and two Zs may be the same or different; wherein the divalent heterocyclic group represented by Y is each of groups represented by formulas (Y-1) to (Y-5): wherein X′ represents a sulfur atom, an oxygen atom, a selenium atom, —NH— or —N(Ra); Ra represents a substituent; R11 to R17 are the same or different and represent a hydrogen atom or a substituent; R11 and R12 may be connected to each other to form a cyclic structure; and plural X's are present, they may be the same or different; wherein R1 and R2 are the same or different and represent a hydrogen atom or a substituent; wherein D represents an arylene group or a fused ring heteroarylene group, provided that a divalent heterocyclic group represented by Y is different from a group represented by D, and a group represented by D is different from the group represented by (VA): wherein Y and Z have the same meanings as above.
