PROBLEM TO BE SOLVED: To provide an adhesive tape with stable adhesive force, excellent in thermal resistance and dimensional stability and capable of reducing film thickness, by using a film containing an aromatic polyamide as a base and controlling the fluctuation of the thickness of the base film and the fluctuation of thickness of the adhesive tape. SOLUTION: The adhesive tape having the adhesive layer at least one side of the base film comprising the aromatic polyamide, the fluctuation F1 of the thickness of the base film is≤5%, and the total fluctuation T1 of the thickness of the base film and the adhesive layer satisfy the inequality of (F1×0.1≤T1≤F1×0.8).
