Abstract
The invention provides a laminate having high elastic modulus retention even at high temperature and having moderate hardness. The laminate includes a layer (A) formed from a fluororesin and a layer (B) formed from a polyamide resin. The fluororesin is a copolymer containing a copolymerized unit of tetrafluoroethylene and a copolymerized unit of vinylidene fluoride, and has a storage elastic modulus (E′) of 60 to 400 MPa measured by dynamic mechanical analysis at 170° C.
