The invention provides a layered product in which a glass cloth and a fluororesin-containing sheet are firmly bonded to each other even without providing a layer of polytetrafluoroethylene fine particles and without recrystallizing the fluororesin. The layered product includes, in a layered structure, a fluororesin-containing sheet, a hot-melt resin layer, and a glass cloth. The glass cloth is a fabric including a bulked glass yarn.

Layered product

An excellent low temperature heat sealing property is imparted to a surface of a non-perfluoro fluorine-containing resin molded article having F/C of not more than 1.8. A non-perfluoro fluorine-containing resin molded article having a surface layer portion having a low temperature heat sealing property on at least a part of the surface layer thereof; said surface layer portion having a low temperature heat-sealing property has a ratio F/C of the number of fluorine atoms to the number of carbon atoms of 0.2&lE;F/C&lE;0.9 and a ratio O/C of the number of oxygen atoms to the number of carbon atoms of 0.09&lE;O/C&lE;0.40, and a remaining portion of the surface layer has a ratio F/C of the number of fluorine atoms to the number of carbon atoms which is larger than that of the surface layer portion having a low temperature heat-sealing property and is 0.8&lE;F/C&lE;1.8.
