PROBLEM TO BE SOLVED: To provide a method of producing bubbles by which bubbles (microbubbles or nano bubbles) with uniform size can be produced stably, and to provide a container for producing bubbles for use in the method of producing bubbles with uniform size.SOLUTION: The method of producing bubbles comprises: a step of injecting a solution 10 containing a target substance up to a predetermined height of a container 20 a step of oscillating the container at a number of revolutions of 5000 rpm or more while the pressure in the container 20 is higher than 1.0 atm so that the solution 10 repeatedly collides with an inner face of the container 20 and a step of oscillating the container 20 again at a number of revolutions of 5000 rpm or more after changing the pressure in the container 20. It is preferred that the pressure in the container 20 is increased to the pressure higher by 1-10 atm than the above pressure and the container is oscillated again.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】均一なサイズのバブル(マイクロバブルまたはナノバブル)を安定的に製造することができるバブルの製造方法の提供、及び、均一なサイズのバブルの製造方法に用いられるバブル製造用容器の提供。【解決手段】対象物質を含む溶液10を、容器20の所定の高さまで注入する工程と、容器20内を1.0atmより大きい圧力にした状態で、溶液10が容器20の内面に繰り返し衝突するように、5000rpm以上の回転数で容器を振動させる工程とを有し、更に容器20内の圧力を変化させた後、5000rpm以上の回転数で容器20を再振動させる工程を有するバブルの製造方法。更に容器20の圧力を前記圧力より1~10atm高くして再振動させることが好ましいバブルの振動方法。【選択図】図3
