The present invention provides a method for producing a silicon compound shown by the following general formula (3) through a hydrosilylation reaction between a hydrosilane compound shown by the following general formula (1) and a carbonyl group-containing alicyclic olefin compound shown by the following general formula (2), in which the hydrosilylation reaction takes place while an acidic compound or acidic compound precursor is gradually added in presence of a platinum-based catalyst. This provides a highly-efficient industrial method for producing an industrially useful, hydrolysable silicon compound having an alicyclic structure (particularly a norbornane ring) and a carbonyl group.
