Title: ADHESIVE TAPE, ARTICLE, AND ARTICLE MANUFACTURING METHOD
Abstract:
The present invention addresses the problem of providing an adhesive tape: that possesses superior adhesiveness before being heated; that can be expanded by being heated; and that is capable of exhibiting superior adhesiveness even after being heated and expanded. The present invention is an adhesive tape that is used for the purpose of filling a gap that an adherend (C1) has or a gap between an adherend (C1) and an adherend (C2), the adhesive tape being characterized in that the adhesive tape includes a thermoplastic heat-expandable adhesive layer (A), and that the rate of expansion of the thermoplastic heat-expandable adhesive layer (A) in a thickness direction, that is, ([thickness of thermoplastic heat-expandable adhesive layer (A1) after being heated]/[thickness of thermoplastic heat-expandable adhesive layer (A) before being heated])×100, is equal to or greater than 150%.
