To provide a composition excellent in adhesiveness with polypropylene.

The composition includes the following components (A), (B) and (C): (A) is a polymer (A-1) containing 70 to 99 mol% of a structural unit originated from propylene and 1 to 30 mol% of a structural unit originated from 1-butene, and exhibiting substantially no melt peak observed, or a polymer (A-2) obtained by graft polymerizing α,β-unsaturated carboxylic acids to the polymer (A-1); (B) is a polymer (B-1) containing 5 to 20 mol% of a structural unit originated from ethylene and 80 to 95 mol% of a structural unit originated from propylene, and exhibiting substantially no melt peak observed, or a polymer (B-2) obtained by graft polymerizing α,β-unsaturated carboxylic acids to the polymer (B-1); and (C) is a polymer (C-1) containing 60 to 90 mol% of a structural unit originated from propylene and 10 to 40 mol% of a structural unit originated from 1-butene, and exhibiting substantially no melt peak observed, or a polymer (C-2) obtained by graft polymerizing α,β-unsaturated carboxylic acids to the polymer (C-1).
