Claim 17:
18. An ultrafine bubble-containing liquid manufacturing apparatus comprising:
an ultrafine bubble generating unit configured to generate ultrafine bubbles with a diameter of less than 1.0 μm, including:
a heater;
a flow path for leading the liquid to the heater;
a controller configured to drive the heater to heat a surface of the heater to a temperature of 300° C. or higher and produce bubbles on the surface of the heater; and
an ejection opening for ejecting liquid containing the ultrafine bubbles generated by production of the bubbles by heating the heater; and

a container configured to collect the liquid in a sealed space cut off from outside air immediately after being ejected from the ejection opening,
wherein the apparatus is configured such at least 99.8% of the bubbles in the liquid collected in the container are the ultrafine bubbles.
