1. An ultrafine bubble generation device comprising a gas-liquid mixed fluid generator for generating a gas-liquid mixed fluid, a rotary mixer, and a bubble shear filter,
the rotary mixer being provided with a hollow part including a vertex inside, and comprising an inflow hole for introducing a fluid into the hollow part, and a discharge hole for discharging the fluid, wherein
a groove having a spiral shape is provided in an inner wall surface of the hollow part, the groove allowing the fluid introduced from the inflow hole to flow through the groove, and
the discharge hole is provided away from a vertex of the spiral shape on an axis of the spiral shape,

the bubble shear filter being provided with a hollow part inside, and comprising an inflow hole for introducing the fluid into the hollow part, and a discharge hole for discharging the fluid, wherein
the hollow part is tubular, and a plurality of circular plates that are in a circular plate shape, are arranged perpendicularly to a central axis of the hollow part such that the central axis passes through a center point of each of the circular plates,
the circular plates adjacent to each other are provided with a plurality of openings and a plurality of pointed end portions, and
an opening of a type 1 of plate, which is selected from the circular plates, and a pointed end portion of a type 2 of plate, which is selected from the circular plates and different from the type 1 of plate, adjacent to the type 1 of plate are arranged to face each other, and connected with a pipeline.
