PROBLEM TO BE SOLVED: To provide a new adhesive tape which has moderately weak adhesive force from its production process (during production) to the end of the production process (immediately after completion of the production) in order to sufficiently prevent poor release and wrinkle formation due to strong adhesion of the adhesive layer to a roller and the like during the production process, resulting in stable product supply and, on the other hand, exhibits sufficiently strong adhesive force to an adherend after the elapse of a predetermined period of time (e.g., when used).SOLUTION: The adhesive tape includes at least three layers; a substrate layer (A), a first adhesive layer (B1) and a second adhesive layer (B2) in this order, wherein the substrate layer (A) comprises a thermoplastic resin, the first adhesive layer (B1) contains ≥12 wt.% of a tackifier, and the second adhesive layer (B2) contains ≤10 wt.% of a tackifier. |
