PROBLEM TO BE SOLVED: To provide a drainboard 1 excellent in impact absorbing properties, stability for walking and abrasion resistance. SOLUTION: The drainboard 1 is composed of cushion parts 3, base plates 5 and cross beam parts 7. Cushion parts 3 are laminated on the base plates 5 respectively. The base plates 5 are juxtaposed in a plurality on the cross beam parts 7 at a space of a prescribed width from each other. The base plates 5 and the cross beam parts 7 are joined by an adhesive or the like. The cushion parts 3 are formed of a soft material. The base plates 5 and the cross beam parts 7 are formed of a hard material. The Asker C hardness of the base plates 5 is 65 or above. The Asker C hardness of the cushion parts 3 is 60 or below. The cushion parts 3 are constituted of a polymer molded body containing foams. The upper side of each cushion part 3 is a skin layer. The surface of the skin layer is embossed.
