Abstract
A dielectric composition includes a polymer having a repeating structure of a unit structure including at least one heterocycle and at least one carbonyl group. The unit structure preferably includes at least one chemical structure including the at least one heterocycle and the at least one carbonyl group bonded to the at least one heterocycle.

A dielectric composition comprising a polymer having a repeating unit of a unit structure including at least one heterocycle and at least one carbonyl group, wherein:
- the unit structure includes at least one chemical structure including the at least one heterocycle and the at least one carbonyl group bonded to the at least one heterocycle,
- the at least one chemical structure includes a structure represented by chemical structural formula (C1) or (C2), and
- in each of the chemical structural formulae (C1) and (C2), m is an integer greater than 0 and less than or equal to 6:
A dielectric composition comprising a polymer having a repeating unit of a unit structure including at least one heterocycle and at least one carbonyl group, wherein:
- the unit structure includes a structure represented by any one of chemical structural formulae than (D1), (D2), (D3), or (D4), and
- in each of the chemical structural formulae (D1), (D3), and (D4), m is an integer greater than 0, and in the chemical structural formula (D2), m is an integer greater than or equal to 2:
A dielectric composition comprising two or more types of polymers each having a repeating unit of a unit structure including at least one heterocycle and at least one carbonyl group, wherein
- the unit structure included in the two or more types of polymers has a structure represented by any one of chemical structural formulae (A), (B), (C1), (C2), (D1), (D2), (D3), or (D4), and
- in each of the chemical structural formulae (C1), (C2), (D1), (D2), (D3), and (D4), m is an integer greater than 0:
