To provide a simple, efficient method for manufacturing a (meth)acryloyl group-containing polyol compound, a (meth)acryloyl group-containing polyol compound produced by the manufacturing method, and an urethane (meth)acrylate produced by using the compound.A method for manufacturing a (meth)acryloyl group-containing polyol compound (x3) includes the steps of producing a hydroxyl group-containing ketal compound (x1) by reacting a polyol compound (A) having at least three hydroxyl groups in the molecular structure with a cyclic ketone compound (B) at the proportion in which the ratio [(OH)/(CO)] of the number of moles of hydroxyl groups (OH) included in the polyol compound (A) to the number of moles of carbonyl groups (CO) included in the cyclic ketone compound (B) falls within the range of 3 to 12 in an organic solvent (S) in the presence of an acid catalyst, producing a (meth)acrylate compound (x2) by (meth)acrylating hydroxyl groups included in the resulting hydroxyl group-containing ketal compound (x1), and hydrolyzing the resulting (meth)acrylate compound (x2).
