To provide a friction resistance reducing device and a ship including the same capable of effectively reducing a friction resistance of a ship.SOLUTION: The friction resistance reducing device includes a first air discharge part formed on the bottom of a hull and discharging air into water, a second air discharge part formed behind the first air discharge part and discharging air into water, and an air supply source to supply air to the first air discharge apart and to the second air discharge part. The first air discharge part and the second air discharge part are arranged in a row in the longitudinal direction of the hull, and at least part of the first air discharge period of the first air discharge part overlaps with at least part of the second air discharge period of the second air discharge part each other.SELECTED DRAWING: Figure 1
