Claim 5:
6. A bubble generation device configured to intermittently discharge bubbles from each of a plurality of bubble discharge ports, the bubble generation device comprising:
a gas storage chamber that stores a liquid therein and stores a gas supplied into the liquid above the liquid;
a turnaround path that communicates with an upper portion of the gas storage chamber, extends downward, turns back, and extends upward;
the plurality of bubble discharge ports that discharge the gas passing through the turnaround path as bubbles;
only one set of the gas storage chamber and the turnaround path are provided; and
a bubble discharge chamber that communicates with each of the plurality of bubble discharge ports, wherein
the turnaround path includes a first communication port communicating with the gas storage chamber and a second communication port communicating with the bubble discharge chamber on a downstream side of a turn-around point of the turnaround path in a gas traveling direction,
opening areas of the plurality of bubble discharge ports are the same as each other, and
a sum of the opening areas is smaller than an opening area of the second communication port.
