Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a balloon coating method capable of dispersing a coating liquid uniformly on a surface of a balloon without relying on conditions such as the shape and surface state of the balloon and the surface tension, etc. of the coating liquid.SOLUTION: The present invention relates to a balloon coating method for forming a coat layer 30 on a surface of a balloon 11 of a catheter 1, the balloon coating method including: supplying, form a first supply part, a preprocessing liquid not containing an agent constituting the coat layer 30 nor hindering the solubility of the agent to the surface of the balloon 11 to apply the liquid onto the surface of the balloon while rotating the catheter 1 around the axis of a shaft 10; and supplying a coating liquid containing the agent from a second supply part to the surface of the balloon 11 coated with the preprocessing liquid to apply the coating liquid onto the surface of the balloon while the rotation of the catheter 1 is maintained, before the preprocessing liquid dries up.SELECTED DRAWING: Figure 2 【課題】バルーンの形状や表面状態、コーティング液の表面張力などの条件によらず、バルーンの表面にコーティング液を均一に分散させることのできるバルーンコーティング方法を提供する。【解決手段】カテーテル１のバルーン１１の表面にコート層３０を形成する方法であって、カテーテル１をシャフト１０の軸心を中心に回転させつつ、バルーン１１の表面に対し第１の供給部からコート層３０が有する薬剤を含まず当該薬剤の溶解性を妨げない前処理用液を供給して塗布するステップと、カテーテル１の回転を維持したまま、前処理液が乾燥する前に、当該前処理液が塗布されたバルーン１１の表面に対し、第２の供給部から薬剤を含むコーティング液を供給して塗布するステップと、を有するバルーンコーティング方法である。【選択図】図２
