A surface-processed structure includes a plurality of blocks that are three-dimensional objects arranged on a target surface. The plurality of blocks are spaced apart from each other and are arranged side by side in a second direction. Each of the plurality of blocks includes a top face including a plurality of fine grooves. The plurality of fine grooves are spaced apart from each other, are arranged side by side in the second direction, and extend from upstream to downstream in a first direction. A width of each of the plurality of fine grooves in the second direction is less than a width of a block clearance in the second direction. Both end portions of the top face in the second direction are located above bottoms of the plurality of fine grooves in a cross section of the block extending along a plane perpendicular to the first direction.
