PROBLEM TO BE SOLVED: To provide a multilayer adhesive sheet, particularly for a multilayer adhesive sheet with a film adhesive having precut-processed, with which the film adhesive and a releasing substrate can be exfoliated without exfoliating an adhesive film and the film adhesive. SOLUTION: The multilayer adhesive sheet includes a releasing substrate (1), a film adhesive (2) arranged on the surface of the releasing substrate (1) and having punching processed, and an adhesive film (3) arranged to cover the film adhesive (2). Further, a releasing assist film (4) having an adhesive layer only on one side is arranged on an area including the whole or a part of the periphery of the film adhesive (2) and the film adhesive (2) between the adhesive film (3) and the releasing substrate (1) in a way that the adhesive layer faces the film adhesive (2) and the adhesive film (3).
