The object of the present invention is to obtain a resin composition that further improves the adhesion to a substrate layer when used as an adhesive layer in a laminate, and a laminate containing layers formed from the resin composition that exhibits superior interlayer adhesive strength. The present invention relates to a resin composition and a laminate containing layers of the resin composition, the resin composition being characterized by containing: 5 to 70 wt% of an propylene polymer (A); 30 to 95 wt% of a soft propylene polymer (B); 0.1 to 20 wt% of an propylene polymer obtained by grafting modification with an olefinic unsaturated monomer (C); 0 to 20 wt% of polyethylene (D); and 1 to 30 wt% of an ethylene-α-olefin random copolymer (E), wherein the total amount of (A), (B), (C), (D), and (E) is set to 100 wt%.
