An air ejecting unit includes an ejecting side chamber installed in a ship bottom of a ship and having air ejecting holes formed in a surface opposite to the ship bottom on a lower side, and a supply section which supplies air into an inner space of the ejecting side chamber. When the air in the ejecting side chamber is ejected from the air ejecting holes, the air is sheared by an external water stream, and small air bubbles are supplied to the ship bottom.
