Abstract
A bubble generation device intermittently generates large bubbles in a liquid phase. The bubble generation device includes a bubble storing container, a pivot, and a pair of edge portion receivers. The bubble storing container stores bubbles generated by a gas supply nozzle in the liquid. The pivot allows the bubble storing container to pivot thereon, thereby releasing the large bubbles from the bubble storing container. The pair of edge portion receivers receives and blocks an edge portion of the bubble storing container to limit pivot of the bubble storing container. An inside of the bubble storing container is partitioned by a partition that is installed in an axial direction of the pivot.
