A surface-processed structure includes a blocks arranged side by side in a first direction parallel to a target surface. The blocks are three-dimensional objects arranged on the target surface. Each of the blocks includes an inclined surface extending from upstream to downstream in the first direction with a distance from the target surface gradually increasing. The inclined surfaces of the blocks are arranged side by side on one line extending in the first direction. Each of the blocks includes a fine grooves provided on the inclined surface. The fine grooves are spaced apart from each other, are arranged side by side in a second direction orthogonal to the first direction, and extend from upstream to downstream in the first direction. The fine grooves extend at a constant depth from an upstream end portion to a downstream end portion of the inclined surface in the first direction.
