An efficient eraser-attached whiteboard is provided to remove all letters or figures written on the whiteboard at a time by accurately connecting joints on top and bottom parts of a long whiteboard eraser to wheels and enabling the eraser to move well from side to side. An efficient eraser-attached whiteboard comprises a whiteboard and a long whiteboard eraser. The eraser is longitudinally formed and connected to top and bottom parts of the whiteboard. The eraser can be laterally moved at edges of the whiteboard. The eraser can perform an erasing operation by holding any portion of the eraser since a handle is longitudinally formed on the eraser. The eraser includes an erasing part which is connected to a body of the eraser through a Velcro tape such that a spent erasing part can be exchanged with a new erasing part easily and promptly.
