Adhesive resin laminate, laminate, and method of producing same

A method of producing a laminate comprising an adhesive resin laminate having at least a first adhesive layer and a second adhesive layer;

• and first and second adherends, said adhesive resin laminate and said first and second adherends being laminated in an order of the first adherend, said first adhesive layer of said adhesive resin laminate, said second adhesive layer of said adhesive resin laminate, and the second adherend,
• wherein said first adhesive layer comprises a base resin and a crosslinking agent, said base resin is a modified polyolefin resin and said crosslinking agent is an epoxy-based compound, said second adhesive layer comprises a polyolefin-based resin, and said first adhesive layer has a viscoelastic modulus measurement value E (150) at 150° C. of 1.0×104 Pa or more and 1.0×108 Pa or less,
• the method comprising:
• (1) a first step of laminating said first adherend and said first adhesive layer and heat-pressing said first adherend and said first adhesive layer to laminate said first adherend and said adhesive resin laminate;
• and
• (2) a step of laminating said second adherend and said second adhesive layer and heat-pressing said second adherend and said second adhesive layer at a temperature higher than a temperature in said first step by 30° C. or more to laminate said second adherend and said adhesive resin laminate, in this order.
