1. A nonaqueous electrolyte solution comprising a compound represented by the following Formula (1) together with an electrolyte and a nonaqueous solvent:

OG Complex Work Unit Chemistry
wherein, X represents an optionally substituted unsaturated hydrocarbon group having 2 to 5 carbon atoms and at least one unsaturated carbon-carbon bond;
Y represents an organic group having 1 to 10 carbon atoms, which consists of atoms selected from the group consisting of a carbon atom, a hydrogen atom, an oxygen atom, a sulfur atom, and a phosphorus atom;
R1 represents a hydrogen atom, a halogen atom, or an unsubstituted or halogen atom-substituted hydrocarbon group having 1 to 10 carbon atoms;
R2 represents an unsubstituted or halogen atom-substituted hydrocarbon group having 1 to 10 carbon atoms;
n represents an integer of 1 to 3;
if the compound includes plural R1, each R1 is the same or different from the other;
if the compound includes plural R2, each R2 is the same or different from the other; and
if the compound includes plural Ys each Y is the same or different from the other,
with a proviso that R2 and one selected from X and Y are not bound with each other to form a ring.
