Reinforcing adhesive sheet

A reinforcing adhesive sheet comprising:

• a thermosetting reinforcing resin sheet containing a reinforcing material in an unhardened or semi-hardened state;
• and
• a bead-forming material provided on the thermosetting reinforcing resin sheet, said bead-forming material being narrower than the thermosetting reinforcing resin sheet and forming a bead-like projection prior to hardening the thermosetting reinforcing resin sheet, wherein said bead-forming material is a flattened material produced by flattening an elastic foamed body containing a holding agent in voids thereof, the flattened form being maintained by the holding agent, and said bead-forming material is capable of recovering its original foamed form upon heating wherein the thermosetting reinforcing resin sheet comprises a first thermosetting reinforcing resin sheet and a second thermosetting reinforcing resin sheet, and the bead-forming material is interposed between the first and second thermosetting reinforcing resin sheets.
