摘要： In one embodiment, a polymer includes a recurring unit containing a bivalent group expressed by a formula (1) shown below. A weight-average molecular weight of the polymer is in a range of 3000 or more to 1000000 or less. R1 is a monovalent group selected from hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkanoyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group. X is an atom selected from oxygen, sulfur, and selenium. Y and Z are each independently a bivalent group selected from a carbonyl group, a sulfinyl group, and a sulfonyl group. A case where Y and Z are both the carbonyl groups is excluded.
