Abstract
A curable composition containing a polyoxyalkylene polymer (A) having a reactive silyl group and a (meth)acrylic ester polymer (B) having a reactive silyl group is provided. In the polyoxyalkylene polymer (A), an average ratio per molecule of a number of reactive silyl groups to a number of ends of a polymer backbone is 0.80 or more. In the (meth)acrylic ester polymer (B), an average number per molecule of the reactive silyl groups bonded at ends of a polymer backbone is from 0.30 to 1.00, and the average number per molecule of the reactive silyl groups bonded inside the polymer backbone is from 0 to less than 0.30.
