PROBLEM TO BE SOLVED: To provide a gas-liquid mixing device by which the increase of fine bubbles to be mixed can easily be attained without complicating the production. SOLUTION: A liquid is made to flow from a flow passage 21A on the side of an inlet 11 to a jet injection hole 3 tightened so as to be small to generate a jet blast whose static pressure is remarkably low. Thus, cavitation is generated, and further, a large quantity of air is drawn from liquid injection holes 7 toward the inside of a cavitation generation chamber 2. Then, at least a part of the air drawn from the liquid injection holes 7 is made into fine bubbles so as to be added/mixed into the liquid as well as the fine bubbles by the cavitation. Thus, the fine bubbles remarkably larger than the conventional ones can be mixed into the liquid as being a simple structure. COPYRIGHT: (C)2005,JPO&NCIPI
