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): R
1
OH in the presence of an acidic zeolite, the cyclopentyl alkyl ether compound being represented by a formula (1): R
1
—O—R
2
, wherein R
1
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 R
2
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.

The present invention is a method for producing a cycloalkyl alkyl ether compound comprising reacting substituted or unsubstituted cyclopentene or substituted or unsubstituted cyclohexene with an alcohol compound represented by a formula (2): R
1
OH (wherein R
1
is 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) in a gaseous state in presence of an acidic ion-exchange resin to produce a cycloalkyl alkyl ether compound represented by a formula (1): R
1
—O—R
2
(wherein R
1
is the same as defined above, and R
2
is a substituted or unsubstituted cyclopentyl group or a substituted or unsubstituted cyclohexyl group), the acidic ion-exchange resin having a specific surface area of 20 to 50 m
