Adhesive resin composition and film

An adhesive resin composition, comprising

• 50 to 89.9 parts by mass of a propylene-based polymer (A) satisfying the following (al) and (a2),
• 0.1 to 20 parts by mass of a modified polyolefin (B) obtained by modifying a polyolefin (b) with an unsaturated carboxylic acid and/or a derivative thereof, and
• 10 to 30 parts by mass of an ethylenic polymer (C) satisfying the following (c1) to (c3), provided that the sum of (A), (B) and (C) is 100 parts by mass:
• (a1) the propylene polymer (A) comprises a propylene-based polymer (a-1) having a first melting point (Tm) of 120° C. or higher observed in differential scanning calorimetry, and a propylene-based polymer (a-2) having a second melting point (Tm) of lower than 120° C. observed or having no melting point observed in differential scanning calorimetry,
• (a2) a proportion of the propylene-based polymer (a-1) in the propylene-based polymer (A) is 50 to 70.0% by mass,
• (c1) the ethylenic polymer (C) comprises a copolymer (c-1) of ethylene and at least one α-olefin selected from α-olefins having 3 to 20 carbon atoms, and optionally an ethylene homopolymer (c-2),
• (c2) a melt flow rate measured at 190° C. under a load of 2.16 kg in accordance with ASTM D1238 is 0.1 to 10 g/10 minutes, and
• (c3) a proportion of the copolymer (c-1) in the ethylenic polymer (C) is 40 to 100% by mass,
• wherein the adhesive resin composition has a melt flow rate measured at 230° C. under a load of 2.16 kg in accordance with ASTM D1238 of less than 7.0 g/10 minutes.
