PROBLEM TO BE SOLVED: To obtain an adhesive tape that can be safely used even in the field of precision electronic equipments, for example, hard disk, or the like, by providing a specific acrylic adhesive layer on one face of a support base material. SOLUTION: On one face of a support base material 1, an acrylic peel ply 3 is formed with a high-gel fraction acrylic adhesive prepared by crosslinking an acrylic adhesive, while on the other face of the support base material 1, an acrylic, rubber -or silicone-based adhesive layer 2 is provided. The tape having the peel ply 3 on one face is clad to the adhesive layer 2 of the body of the adhesive tape having the adhesive layer 2. The above peeling agent is prepared by mixing 100 pts.wt. of an acrylate ester and acrylic acid copolymer with 0.5-25 pts.wt. of a polyfunctional epoxy group-bearing crosslinking agent, and the acrylic ester preferably has a carbon number of 4-12.
