Today, high class swimming race is competed in the range of 1/100 second. It is important to develop a swimming suit with low drag. This paper describes the relationship between fluid drag and flow pattern around body. The experiment is carried out in water channel by using a woman's artificial model. The model set under the carriage is pulled from 0.75 m/s to 2.02 m/s in water channel. The drag by the difference of water depth and velocity in swimming is explained by flow visualization around the model. Also the drag by the difference of swimming suit in swimming is explained by flow visualization around breast.
