An object of the present invention is to provide a resin composition suitable for adhering a layer of a base material, such as polyolefins, and a layer of a barrier resin, such as ethylene-vinyl alcohol copolymers. The object is achieved by a resin composition (A) including: a thermoplastic resin (a1) having functional groups of at least one kind selected from the group consisting of a boronic acid group and boron-containing groups capable of being converted into a boronic acid group in the presence of water, a polyolefin (a2) not having the functional groups, and a thermoplastic elastomer (a3) not having the functional groups, wherein the thermoplastic resin (a1) is contained 1 to 20 parts by mass and the thermoplastic elastomer (a3) is contained 3 to 50 parts by mass in terms of 100 parts by mass of the polyolefin (a2). |
