To provide a method for industrially and efficiently producing an acetal and/or ketal compound.

The method for producing the acetal and/or ketal compound comprises reacting an olefin having a carbonyl group and an ethylenic double bond in the same molecule with an alcohol to protect the carbonyl group and reacting the olefin having the protected carbonyl group and the ethylenic double bond with oxygen and an alcohol to obtain the corresponding acetal and/or ketal compound. In the production method, a number obtained by dividing a number of moles of a hydroxy group of the residual alcohol in the product obtained by protection by a number of moles of the resultant acetal is kept to ≤2.
