Ultrafine bubble water generator and structure body thereof

A structural body of a ultrafine bubble water generator capable of making bubbles contained in tap water finer to produce water including many ultrafine bubbles, the structural body comprising:

• a water intake surface body disposed on the inlet side of tap water, the water intake surface body having branching holes for branching tap water flow into the interior of the structure body into plural inflows;
• a water output surface body on the outlet side from the structural body, the water output surface body having branching holes for branching the outflow of ultrafine bubble water produced inside of the structural body into plural outflows;
• and
• a hollow cylindrical body supporting the outer circumferential surfaces of the water intake surface body and the water output surface body,
• wherein the cylindrical body, the water intake surface body and the water output surface body of the structural body are selected to have an outer diameter that fits the inner wall of a tap water supply pipe for supplying the tap water or various water flowing tubes, and previously inserted and set in the tap water supply pipe.
