To provide an adhesive resin composition which is excellent in adhesion, heat resistance, film formability and film quality, and to provide a multilayer article having an adhesive resin layer comprised of the adhesive resin composition.

The adhesive resin composition comprises 10-99.5% by weight of a resin component (A), 0.5-30% by weight of another resin component (unsaturated carboxylic acid-modified polypropylene), and 0-89.5% by weight of a still another resin component (olefin resin). The resin component (A) is a propylene-based product obtained by step polymerization, which contains 10-60% by weight of a propylene homopolymer component (a1) and 40-90% by weight of a propylene-ethylene copolymer component (a2). With respect to the resin component (A), the (a1)-derived content soluble in xylene at room temperature is 1-20% by weight, the (a2)-derived component insoluble in xylene at room temperature is less than 20% by weight, the (a2)-derived component soluble in xylene at room temperature is 10-60% by weight, and the content of α-olefins other than propylene in the (a2)-derived component soluble in xylene at room temperature is ≥20% by weight.
