Abstract
In a fine bubble generator having a structure in which a columnar portion protrudes from an orifice of a tubular member, the presence of the columnar portion inhibits a flow of a fluid, so that a flow rate of the fluid that generates fine bubbles is limited. In addition, foreign matter may be sandwiched between the columnar portions. It takes time and effort to manufacture the columnar portions. Furthermore, when the columnar portion is supported in a cantilever state, it is difficult to ensure mechanical rigidity and also to ensure durability. A fine bubble generator includes: an inlet portion that gradually reduces in diameter from an inlet of a tubular body; an orifice continuous to the inlet portion; and an enlarged-diameter portion continuous to the orifice, and the inlet portion, the orifice and the enlarged-diameter portion are sequentially formed. A boundary between the orifice and the enlarged-diameter portion is a radially elevation surface, and a diameter of the enlarged-diameter portion is 3 to 10 times a diameter of the orifice. A concave portion is preferably formed in an outlet peripheral wall.
