Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aqueous-emulsion adhesive exhibiting initial tack during the production of a bonded object, keeping its adhesiveness during the use of the object, and suited for recycling (re-use or disposal after separation) because the object, when becomes useless, can be easily separated into adherends even after being cooled to room temperature by energy irradiation. SOLUTION: The aqueous adhesive composition used is prepared by formulating (A) an aqueous emulsion being an adhesive styrene/butadiene copolymer latex or acrylic emulsion in which the polymer has a glass transition temperature in the range of -60 to 0°C with (B) a filler and (C) a blowing agent.
