PROBLEM TO BE SOLVED: To provide a method for an adhesion treatment by which anchoring force is improved and to provide a pressure-sensitive adhesive tape without causing residual pastes by coating an adhesion treating surface prepared by the method with a pressure-sensitive adhesive having enhanced cohesive force. SOLUTION: The character is to coat at least one surface of a heat-resistant sheet with an adhesion treating solution composed of an adhesion treating agent and a solvent, then rapidly evaporate the solvent in the adhesion treating solution, form holes or/and cracks in a continuous cell state in a solid component and heat the adhesion treating agent at a temperature for causing molding thereof. When the adhesion treating surface is coated with the pressure-sensitive adhesive, the gel fraction of the pressure-sensitive adhesive is preferably 20-60%. COPYRIGHT: (C)2004,JPO
