1. An adhesive resin composition comprising:
a propylene polymer (A),
an ethylene polymer (B) that is a polymer with 10 mol % or less of comonomer, and
a thermoplastic resin (C) comprising a copolymer containing not less than 60 mol % and not more than 99 mol % of structural units derived from 4-methyl-1-pentene, and not less than 1 mol % and not more than 40 mol % of structural units derived from a C2-C20 α-olefin other than 4-methyl-1-pentene, the structural units derived from 4-methyl-1-pentene and the structural units derived from a C2-C20 α-olefin other than 4-methyl-1-pentene representing in total 100 mol % of the copolymer, the thermoplastic resin (C) showing a melting point Tm of not more than 199° C. or showing substantially no melting point as analyzed with a differential scanning calorimeter (DSC),
the total of the components (A), (B) and (C) taken as 100 parts by mass including 45 to 75 parts by mass of the component (A), 5 to 20 parts by mass of the component (B), and 15 to 45 parts by mass of the component (C).
