Includes a polypropylene-based adhesive layer (I) and a base material layer (II), which satisfies at least the following requirements (1) to (5) and includes a heat treatment step of heat treatment at a temperature of 80 to 140 ° C. for 5 to 120 minutes. A method for manufacturing a laminate. (1) The adhesive layer (I) contains 97 to 70% by weight of the propylene copolymer (A) and 3 to 30% by weight of the copolymer (B) having a structural unit derived from butene (provided that the copolymer is (2) The copolymer (A) has a melting point (TmA) measured by a differential scanning calorimeter (DSC) of 70 to 120 ° C. (3) The copolymer (B) has a melting point (TmB) of 130 ° C. or less as measured by a differential scanning calorimeter (DSC), wherein the content of the butene-derived structural unit is less than 1 mol%. The content of the structural unit derived from butene is 1 mol% or more. (4) The adhesive layer (I) comprises a structural unit derived from at least one type of graft monomer selected from the group consisting of unsaturated carboxylic acids and derivatives thereof. Including polymer (C) having (5) The base layer (II) contains a polyester resin |
