PROBLEM TO BE SOLVED: To provide an extensible adhesive sheet having excellent extensibility and capable of coming into close contact with a place having a curved face or an uneven face. SOLUTION: The extensible adhesive sheet is formed by laminating a thermal plastic resin layer, an unwoven fabric layer and an adhesive layer, wherein the unit weight of the unwoven fabric layer is 40-120 g/m<SP>2</SP>, the unit weight of the adhesive layer is 15-300 g/m<SP>2</SP>and the elongation in the fracture point is≥200%. The extensible adhesive sheet is suitable for an adhesive tape for building member joint and is used suitably for joining the boundary part of the building members which requires air tightness or water tightness.
