A ship bottom structure and a ship are provided in which, even for lean ships which have a ship bottom inclined portion on the ship bottom, can favorably achieve a friction resistance reduction effect by means of an air lubrication system. This structure of the ship bottom (13) is equipped with an air lubrication system which spouts air bubbles (100) on the ship bottom (13) of the hull (10), and said ship bottom (13) has a ship bottom inclined portion (13b) which is inclined upwards towards the outside in the hull width direction (Y), wherein the angle (φ) of the ship bottom inclined portion (13b) in the maximum horizontal cross-section position, in which the horizontal cross-section of the hull (10) is maximal, is set to greater than 0° and less than 15°.
