Provided is a chewing gum that has excellent fragrance diffusion properties. The present inventors discovered that, when a chewing gum-balloon is formed during chewing, the total amount of diffused fragrance component(s) is almost twice as much as in the case of not forming a balloon and, therefore, the formation of a balloon is effective for improving the fragrance diffusion properties. As the results of the subsequent intensive studies, provided are: a chewing gum comprising a sugar ester and a fragrance, characterized by further containing 3.0-8.0 wt% inclusive of a vinyl acetate resin having a molecular weight of 45,000 or more； and a chewing gum comprising a sugar ester, a fragrance and a vinyl acetate resin, characterized in that the HLB value of the sugar ester is 3-11 inclusive.本發明提供一種香氣擴散性高的口香糖。本發明之發明者們發現，在口香糖咀嚼中形成氣泡與沒有形成氣泡相比，擴散的香氣成分總量增加至約2倍，並且發現氣泡的形成對於香氣擴散性的提升是有效的。更進一步進行潛心研究的結果，達成了特徵為包含糖酯、香料，並且進一步包含分子量45,000以上之醋酸乙烯酯樹脂3.0wt%以上8.0wt%以下之口香糖，以及，特徵為包含糖酯、香料、以及醋酸乙烯酯樹脂，且其糖酯之HLB值為3以上11以下之口香糖等發明。
