PURPOSE: A drain board is provided to improve durability and intensity by forming reinforcement protrusions on the outer surfaces of protrusions formed on the drain board. CONSTITUTION: A drain board comprises a board body(110), a filter(120), and water storage protrusions(130). The board body is formed using a synthetic resin material, and multiple protrusions(112) are formed on the surface thereof. The filter covers the board body so that water can flow through the protrusions of the board body. The water storage protrusions are formed between the protrusions of the board body to store a portion of water flowing through the protrusions. |
