Fragrance composition

A fragrance composition comprising a cis isomer and a trans isomer,

• wherein the cis isomer comprises a compound represented by formula (Ia), a compound represented by formula (Ib), a compound represented by formula (IIa), and a compound represented by formula (IIb),
• the trans isomer comprises a compound represented by formula (IIIa), a compound represented by formula (IIIb), a compound represented by formula (IVa), and a compound represented by formula (IVb), and
• a mass ratio of the cis isomer to the trans isomer [cis isomer:trans isomer] is 65:35 or more and 95:5 or less,
• wherein in the formulae (Ia), (Ib), (IIa), (IIb), (IIIa), (IIIb), (IVa), and (IVb),
• R1 is an alkyl group having 1 or more and 5 or less of carbon atoms, and
• R2 is a hydrogen atom or an alkyl group having 1 or more and 4 or less of carbon atoms,
• wherein a mass ratio of a sum of the compound represented by formula (Ia) and the compound represented by formula (Ib) to a sum of the compound represented by formula (IIa) and the compound represented by formula (IIb) is 55:45 or more and 68:32 or less.
