The present invention is aimed at reducing a fluid frictional resistance generated on a surface of a body which relatively moves in a fluid.A structure on the body for reducing the fluid frictional resistance generated on a body B which relatively moves in the fluid wherein:grooves M formed on a surface S of the body in order that grooves M lead the fluid flowing along the surface so as to turn flowing fluid to a direction of the moving direction X of the body.
