Claim 0:
1. A fine bubble generation method using a fine bubble generation device comprising a porous body having continuous pores, a liquid supply part which supplies a liquid to the porous body and causes the liquid to flow through the continuous pores, and a liquid discharge part which discharges the liquid caused to flow through the continuous pores, wherein
an average flow diameter of the porous body as measured with a palm porometer is 5 μm to 50 μm, and
the average flow diameter is an average of the pore diameters of a smallest part of the continuous pores in the porous body,
the method comprising the steps of:
supplying a liquid in which a gas is already dissolved to the porous body from the liquid supply part of the fine bubble generation device, and
causing the supplied liquid to flow through the continuous pores of the porous body to obtain a liquid containing fine bubbles from the liquid discharge part, wherein
the fine bubbles are derived from the gas during passage of the supplied liquid through the porous body, and
the fine bubbles emerge from the porous body with an average particle diameter of less than 1 μm.
