ABSTRACT:
There is provided a surface treated product that moves relatively in a fluid, wherein a surface of the surface treated product has continuous dimples, each dimple having a diameter of 10 to 2500 μm and a depth of 50 μm or less. The surface treated product significantly reduces resistance of a fluid to an object in the fluid, and significantly improves a flow state of the fluid.
