Laminate body and method for producing laminate body

A method of producing a laminate, comprising

• heat pressing a metal and a sheet,
• wherein the sheet comprises a copolymer containing a polymer unit based on tetrafluoroethylene and a polymer unit based on a perfluoro(alkyl vinyl ether),
• the copolymer contains a carboxyl group at a terminus of a main chain and has a melt flow rate of not lower than 20 g/10 min and a melting point of not higher than 295° C., and
• the metal is at least one selected from the group consisting of copper, stainless steel, aluminum, iron, and an alloy thereof.

A method of producing a laminate, comprising

• covering/molding a core wire comprising a metal with a copolymer,
• wherein the copolymer contains a polymer unit based on tetrafluoroethylene and a polymer unit based on a perfluoro(alkyl vinyl ether),
• the copolymer contains a carboxyl group at a terminus of a main chain and has a melt flow rate of not lower than 20 g/10 min and a melting point of not higher than 295° C., and
• the metal is at least one selected from the group consisting of copper, stainless steel, aluminum, iron, and an alloy thereof.
