Zusammenfassung:	To provide a preparation method of an ozone indicator capable of easily evaluating by visual observation whether a treatment is properly done as intended after a sterilization treatment by arranging a sterilization atmosphere due to an ozone gas.SOLUTION: An ozone indicator 21 is one that changes color according to the product of a concentration of ozone gas and its exposure time. The ozone indicator is prepared by dissolving bromophenol blue or Coomassie brilliant blue as a coloring agent in a pH buffer solution to prepare a basic solution, dropping this basic solution onto a filter made of a hydrophilic membrane made of, for example, polyvinylidene fluoride resin, and then drying this filter.SELECTED DRAWING: Figure 5 【課題】オゾンガスによる殺菌環境等に配することにより殺菌処理等の後に処理が意図通り適切になされたか否かを目視により簡便に評価できるオゾンインジケーターの調製方法を提供する。【解決手段】オゾンインジケーター２１は、オゾンガスの濃度とその曝露時間との積に応じて変色するものをいう。オゾンインジケーターは、ブロモフェノールブルーまたはクマシーブリリアントブルーを着色剤としてｐＨ緩衝液に溶解して基本液を調整し、この基本液を例えばポリフッ化ビニリデン樹脂製の親水性膜からなるフィルターに滴下し、その後にこのフィルターを乾燥して調製される。【選択図】図５
