Zusammenfassung:	To provide a chlorine-containing gas stable for a long period by using crystals of hypochlorite.SOLUTION: A method according to the present invention comprises a removing step of removing carbon dioxide from a cartridge container (30) containing hypochlorite crystals (1). In the removing step, a decarboxylated gas having a carbon dioxide concentration of 10 ppm or less is supplied to the cartridge container (30) until the effective chlorine concentration of a gas discharged from the cartridge container (30) becomes 0.2 ppm or less.SELECTED DRAWING: Figure 3 【課題】次亜塩素酸塩の結晶を用いて、長期間、安定した塩素含有ガスを発生させる。【解決手段】本発明の方法は、次亜塩素酸塩の結晶（１）を収納するカートリッジ容器（３０）から二酸化炭素を除去する除去工程を含み、この除去工程では、カートリッジ容器（３０）から排出される気体の有効塩素濃度が０．２ｐｐｍ以下となるまで、二酸化炭素の濃度が１０ｐｐｍ以下である脱炭酸ガスを、カートリッジ容器（３０）に供給する。【選択図】図３
