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 adhesive composition used is prepared by formulating an aqueous emulsion with a release agent and a blowing agent. This composition exhibits initial tack during the production of a bonded object and can find its utility in fields such as recyclable building members, automotive components, office supplies, and living sundries because the object can be easily separated into adherends with very little residual adhesive even after being cooled to room temperature by energy irradiation.
