PROBLEM TO BE SOLVED: To eliminate the risk of an electric shock with a simple configuration in an ultrasonic type nebulizer provided with a tank unit which is configured to be attachable/detachable to/from a body.SOLUTION: A tank unit includes a working tank incorporating an ultrasonic vibrator, a medicament tank and a medicament tank cover that are arranged so as to be sequentially overlapped thereon. In the state where the tank unit is mounted on the body, output of an oscillation circuit in the body is applied to the ultrasonic vibrator via a body side contact electrode and a tank side contact electrode. The body includes a blower fan which blows air into the medicament tank through an air duct of the medicament tank cover, and a medicament tank cover detection unit which detects whether or not the air duct of the medicament tank cover is adjacent to the body with regard to the presence/absence of mounting of the tank unit to the body (S1).SELECTED DRAWING: Figure 10【課題】本体に対して着脱可能に構成された槽ユニットを備えた超音波式ネブライザにおいて、簡単な構成で、感電の危険を無くすこと。【解決手段】槽ユニットは、超音波振動子が組み込まれた作用槽と、薬剤槽と、薬剤槽カバーとを、順に上に重ねて配置されるように含む。本体に対して槽ユニットが装着された状態で、本体内の発振回路の出力が本体側接点電極、槽側接点電極を通して超音波振動子に印加される。本体は、薬剤槽カバーの風路を通して薬剤槽内へ送風を行う送風ファンと、本体に対する槽ユニットの装着の有無として、薬剤槽カバーの風路が本体に隣接しているか否かを検知する薬剤槽カバー検知部を備える（Ｓ１）。【選択図】図１０
