PROBLEM TO BE SOLVED: To provide a space-saving type aroma emission device having portability, preventing the leakage of liquid aroma component to the outside, and effectively volatilizing the aroma component irrelevant to used environmental condition, for example, even under low-temperature environment or high-temperature environment. SOLUTION: This aroma emission device is characterized in that at least a part of a sheet formed by packing aroma component containing gel obtained by gelating the liquid aroma component by gelatinizer is formed of polyether-based thermoplastic urethane elastomer and the glass transition temperature Tf of the polyether-based thermoplastic urethan elastomer is within -30 to 50°C.
