    Abstract: A bonding method using adhesive sheets respectively containing first and second thermoplastic resins. The volume content VA1 of the first thermoplastic resin in the adhesive sheet and the volume content VA2 of the second thermoplastic resin in the adhesive sheet are from 60 vol % to 100 vol %. Change rates Vx1 and Vx2 represented by formulae below are less than 80%. VB1 is the volume content of the first thermoplastic resin in a layer in direct contact with the first adhesive layer, and VB2 is the volume content of the second thermoplastic resin in a layer in direct contact with the second adhesive layer. The method includes applying a high-frequency wave to the adhesive sheets between adherends to bond them together,

    Abstract: Base film for a dicing sheet comprises a cutting-fragment suppression layer and an expandable layer laminated on one main surface of the cutting-fragment suppression layer. The expandable layer comprises at least one resin-based unit layer. The at least one resin-based unit layer includes a resin-based unit layer that is disposed nearest to the cutting-fragment suppression layer. The resin-based unit layer comprises a linear polyethylene, polypropylene, and thermoplastic elastomer. The cutting-fragment suppression layer comprises a ring-containing resin that is a thermoplastic resin having at least one type of an aromatic series-based ring and an aliphatic series-based ring and an acyclic olefin-based resin that is an olefin-based thermoplastic resin other than the ring-containing resin. The base film for such a dicing sheet is excellent in the expandability and recoverability.
