PROBLEM TO BE SOLVED: To provide the ozone dissolving device which is mounted in a ballast tank and constituted so as to uniformly dissolve ozone in seawater with high efficiency. SOLUTION: The ozone dissolving device is constituted so that an ozone injection pipe 2 is provided to a water distribution pipe 1 for supplying seawater W to the ballast tank and ozone S ejected from the ozone injection pipe 2 is dissolved in the seawater W in the water distribution pipe 1. A screw propellar 5 for forming a vortex stream is provided on the upstream side of the ozone injection pipe 2 and a turbulent flow forming means 10a is provided on the downstream side of the ozone injection pipe 2. The turbulent flow forming means 10a is formed of a plurality of plates or rod-like bodies 8a-8f arranged on the spiral virtual line 7 drawn on the inner wall surface of the water distribution pipe 1 at a predetermined interval.
