Claim 0:
1. An electrolyte solution comprising a compound (1) represented by the following formula (1) and at least one compound (11) selected from the group consisting of compounds represented by the following formulas (11-1) to (11-5),
the formula (1) being, , wherein R101 and R102 are each individually a substituent represented by
—H,
—F,
a group represented by the formula: —Op101—(SiR1032O)n101—SiR1043, wherein R103 and R104 are each individually an alkyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom, an alkenyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom, an alkynyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom, or an aryl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom; n101 is an integer of 0 or greater; and p101 is 0 or 1,
a C1-C7 alkyl group,
a C2-C7 alkenyl group,
a C2-C7 alkynyl group,
a C6-C15 aryl group,
—SO2X101, wherein X101 is —H, —F, or an alkyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom,
—SO3X102, wherein X102 is —H, —F, or an alkyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom, or
a C2-C7 hydrocarbon group that forms a cyclic structure by bonding of R101 and R102, the cyclic structure optionally containing a multiple bond, and
the substituent optionally contains at least one divalent to hexavalent hetero atom in a structure or optionally has a structure obtained by replacing at least one hydrogen atom by a fluorine atom or a C1-C7 functional group,
the formula (11-1) being, , wherein R111 and R112 are the same as or different from each other and are each a hydrogen atom, a fluorine atom, or an alkyl group optionally containing a fluorine atom, and R113 is an alkyl group free from a fluorine atom or an organic group containing an unsaturated carbon-carbon bond,
the formula (11-2) being, , wherein R121 is an optionally fluorinated C1-C7 alkyl group, an optionally fluorinated C2-C8 alkenyl group, an optionally fluorinated C2-C9 alkynyl group, or an optionally fluorinated C6-C12 aryl group, and optionally contains at least one selected from the group consisting of O, Si, S, and N in a structure,
the formula (11-3) being, , wherein R131 and R132 are (i) each individually H, F, an optionally fluorinated C1-C7 alkyl group, an optionally fluorinated C2-C7 alkenyl group, an optionally fluorinated C2-C9 alkynyl group, or an optionally fluorinated C5-C12 aryl group, or (ii) hydrocarbon groups binding to each other to form a 5- or 6-membered hetero ring with a nitrogen atom, and R131 and R132 each optionally contain at least one selected from the group consisting of O, S, and N in a structure,
the formula (11-4) being, , wherein Rf141 is CF3—, CF2H—, or CFH2—, and R141 is an optionally fluorinated C2-C5 alkenyl group or an optionally fluorinated C2-C8 alkynyl group and optionally contains Si in a structure,
the formula (11-5) being

CH3CFX151COOR151, wherein R151 is a C1-C4 alkyl group, and X151 is H or F.
