PROBLEM TO BE SOLVED: To provide a friction resistance-reduced type ship utilizing an air lubrication method in which air bubbles is generated by blowing out air substantially equally from a plurality of holes provided at a bottom of the ship without depending on positions of the holes.SOLUTION: The friction resistance-reduced type ship includes a plurality of air blowing out parts 1b provided at a bottom of a hull. The air blowing out part 1b includes: an air supply pipe 4 for supplying air; and a container part 2 whose top surface is connected to the air supply pipe 4 and that has a plurality of air blowing out holes 5-1 to 5-8 and 6-1a to 6-7a in a bottom surface 7 of the container part 2. The air blowing out holes are arranged along straight lines L11 and L12 that are parallel to a ship width direction and extend in a ship length direction. The air blowing out holes are disposed at a position where the air blowing out holes do not overlap each other when viewed from a bow side. An area of each of the air
