Abstract: The present invention is a method for producing a cyclopentyl alkyl ether compound comprising reacting substituted or unsubstituted cyclopentene with an alcohol compound represented by a formula (2): R1OH in the presence of an acidic zeolite, the cyclopentyl alkyl ether compound being represented by a formula (1): R1—O—R2, wherein R1 represents a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, or a substituted or unsubstituted cycloalkyl group having 3 to 8 carbon atoms, and R2 represents a substituted or unsubstituted cyclopentyl group. The present invention provides a method that can produce a cyclopentyl alkyl ether with high reaction efficiency through a liquid-phase reaction even when the raw material feed rate (amount) is increased.
