The utility model relates to the technical field of corrugated boards, and discloses a corrugated board which comprises two outer surface paper layers, corrugated medium paper is arranged between the two outer surface paper layers, water-resisting layers are fixedly installed on the outer sides of the outer surface paper layers, buffer rings are evenly and fixedly installed on one side of the corrugated medium paper, and the buffer rings are fixedly installed on the outer sides of the outer surface paper layers. The front portion and the rear portion of each buffering ring are hollow, and the buffering rings are filled with water absorption strips. The water-resisting layer, the buffering ring and the water absorbing strip are arranged, so that during use, the outer side of the outer paper layer can be isolated and protected through the water-resisting layer, the situation that the outer paper layer makes contact with external liquid and is eroded and broken in the transportation process is avoided, through t
