To provide an aroma transmission method in which, by using a simple device constructed with an air gun, a perceivable aroma is transmitted to a recipient in a form that does not make the recipient feel discomfort and that is easy to smell.SOLUTION: Provided is an aroma transmission method in which an aroma is transmitted to a recipient by ejecting a vortex ring containing the aroma from an air gun. In this aroma transmission method, a vortex ring that is made visible by containing minute droplets is ejected at a flight speed in velocity per second of 0.3 m/s or more and velocity per second of 1 m/s or less from an ejection port 30 having a port diameter of 1.5 cm or more and 5 cm or less toward a recipient who is present at a distance of 0.2 m or more and less than 1 m from the ejection port 30 of an air gun 11.SELECTED DRAWING: Figure 1【課題】空気砲を備えて構成される簡単な装置を用いて、被伝達者が違和感なくかつ嗅ぎやすい形で、感知可能な香りを被伝達者に伝達する香気伝達方法を提供する。【解決手段】香気を含む渦輪を空気砲から射出することにより香気を被伝達者に伝達する香気伝達方法を提案する。この香気伝達方法では、空気砲11の射出口30から0.2m以上、1m未満の距離にいる被伝達者に向けて、微小液滴を含ませて視認可能にした渦輪を、口径1.5cm以上、5cm以下の射出口30から秒速0.3m以上、秒速1m以下の飛行速度で射出する。【選択図】図1
