1. A method for manufacturing a laminated molded body, the method comprising:
a cutting-out step for cutting out a cushion layer to form a cut-out part;
a base material laminating step for forming a first laminated body by arranging a base material on a lower surface of the cushion layer cut out in the cutting-out step with an adhesive sheet provided therebetween and having an adhesive force by heating;
an insulating material placing step for attaching an insulating material to the cut-out part of the first laminated body;
a first thermocompression bonding step for bonding by thermocompression the first laminated body to which the insulating material is attached;
a removing step for removing the cut-out part from the first laminated body bonded by thermocompression in the first thermocompression bonding step to form an opening part;
a skin laminating step for forming a second laminated body by arranging a skin on an upper surface of the first laminated body from which the cut-out part is removed with an adhesive sheet provided therebetween and having an adhesive force by heating; and
a second thermocompression bonding step for bonding the skin at the opening part to a lower layer material by bonding the second laminated body by thermocompression, the lower layer material being arranged below the cushion layer having the opening part.
