Abstract: An adhesive sheet includes an adhesive layer including a fine structure on a front surface of the adhesive layer. The fine structure includes a plurality of convex structures. Each of the convex structures includes two or more parts. The first part present at the top of the convex structure includes a first adhesive material. The second part present below the first part includes a second adhesive material having higher adhesiveness than the first adhesive material. When a test is conducted in accordance with JIS K 7125 except that a metal sliding piece is pulled at a speed of 1000 mm/min., a coefficient of static friction is 10 or more.

Abstract: A resin composition, including a radical-polymerizable compound, a cation-polymerizable compound, a photo radical photopolymerization initiator, and a photo cation photopolymerization initiator; wherein the resin composition has a range of wavelengths so that one of the photo radical photopolymerization initiator and the photo cation photopolymerization initiator has a molar absorption coefficient of 1 or greater, and the other has a molar absorption coefficient of 0.1 or less. A gap-filling adhesive which is a partially polymerized product of the resin composition. The gap-filling adhesive is capable of easily filling the gap in the body to be adhered.
