PROBLEM TO BE SOLVED: To provide a method for simply and effectively producing a product of Michael addition reaction having a perfluoroalkyl group, a polyfluoroalkyl group or a fluoroalkyl group and a quaternary carbon atom on theα-position of the carbon of these substituents. SOLUTION: The Michael addition product is obtained by reacting a ketene silyl acetal expressed by R<SB>f</SB>(R<SP>12</SP>R<SP>13</SP>R<SP>14</SP>SiO)C=C(OSiR<SP>15</SP>R<SP>16</SP>R<SP>17</SP>)(OR<SP>11</SP>) with anα,β-unsaturated aldehyde orα,β-unsaturated ketene in the presence of a Lewis acid. (In the formula R<SB>f</SB>represents a perfluoroalkyl group, a polyfluoroalkyl group or a fluoroalkyl group, R<SP>11</SP>is H or a monovalent organic group, R<SP>12</SP>, R<SP>13</SP>, R<SP>14</SP>, R<SP>15</SP>, R<SP>16</SP>and R<SP>17</SP>are each an alkyl group or the like.).
