To provide an adhesive sheet which has a thin and yet sufficiently strong adhesive layer, is excellent in heat resistance and fusibility and exhibits a low hygroscopicity.
The adhesive sheet is used for bonding two sheet-like materials, composed of a laminate in which bondable fluoro resin films are laminated and fused on both the sides of a stretched porous polytetrafluoroethylene sheet. The bondable fluoro resin film is a blend of (A) a fluoro resin having an adhesive functional group, (B) a liquid crystal polymer resin and (C) a fluoro resin not having an adhesive functional group. The bondable fluoro resin film is integrated with the stretched porous polytetrafluoroethylene sheet, stretched at least in one direction and has a thickness of ≤50 μm.
