Summary:To provide a defoaming method and a defoaming device which can sufficiently exhibit a defoaming effect even to a fluid having high viscosity.SOLUTION: There are provided a defoaming method and a defoaming device that injects gas into a viscous liquid in a container when a fluid having viscosity ηof 1 Pa s or more and 1,000 Pa s or less at shear rate of 0.01 sis defined as a viscous fluid, and applies pressure oscillation to the viscous fluid via a container.SELECTED DRAWING: Figure 1 【課題】本発明は、粘性の高い流体に対しても十分な脱泡効果を発揮することができる脱泡方法、及び脱泡装置を提供することをその課題とする。【解決手段】剪断速度０．０１ｓ−１での粘度η０．０１が１Ｐａ・Ｓ以上１，０００Ｐａ・Ｓ以下である流体を粘性流体としたときに、容器中の粘性流体に気体を注入し、容器を介して圧力振動を印加することを特徴とする、脱泡方法、及び脱泡装置。【選択図】図１
