SOLUTION: A storage tank 10 includes a tank body 10a formed in a circular cylinder shape with a bottom, and for storing a liquid such as oil, a floating roof 13 of a circular plate shape, which floats on a liquid surface of the liquid stored in the tank body 10a, and a drain pipe 18 communicating with a drain port 14 that opens in the center part "c" of the floating roof 13 and discharges rain water collected in the drain port 14 to the outside of the tank body 10a. The floating roof 13 includes a curved surface 13a formed in a curved slope shape descending from the outer peripheral edge part toward the drain port 14, and a reinforcing plate 20 provided so as to stand from the curved surface 13a and for reinforcing the floating roof 13.
