PROBLEM TO BE SOLVED: To provide an aerosol which obtains sufficient cooling effect for eliminating noxious insects.SOLUTION: An aerosol 100 includes: an aerosol container for storing an aerosol agent and an injection button 20 disposed on the aerosol container. The injection button 20 includes: a tip part including an injection port 58a from which the aerosol agent is injected and an introduction port 58b from which the aerosol agent to be injected from the injection port 58a is introduced and a passage 60 where one end is connected with the introduction port 58b and the other end is connected with the aerosol container. The passage 60 includes: a communication passage 38b which extends from the aerosol container in a vertical direction and a straight part 70 which extends from the introduction port 58b, is connected with the communication passage 38b, and has an inner diameter equivalent to an inner diameter of the introduction port 58b. The injection port 58a has an inner diameter larger than an inner diameter of the introduction port 58b.COPYRIGHT: (C)2015,JPO&INPIT【課題】害虫を防除するための充分な冷却効果を得ることが可能なエアゾールを提供する。【解決手段】エアゾール100は、エアゾール剤を収容するエアゾール容器と、エアゾール容器上に配置された噴射ボタン20と、を備え、噴射ボタン20が、エアゾール剤を噴射する噴射口58a、及び、噴射口58aから噴射されるエアゾール剤を導入する導入口58bを有する先端部と、一端が導入口58bに接続されると共に他端がエアゾール容器に接続される流路60と、を有し、流路60が、エアゾール容器から上下方向に延びる連通路38bと、導入口58bから延びて連通路38bに接続されると共に導入口58bの内径と等しい内径を有する直線部70と、を有し、噴射口58aが導入口58bの内径よりも大きい内径を有する。【選択図】図3
