PURPOSE: A deck board for a treadmill is provided to adhere a sponge on the upper end of a deck board, thereby minimizing inter-floor noise due to operating a treadmill. CONSTITUTION: A deck board for a treadmill is positioned between the upper and lower part of a running belt connected between a driving roller and a passive roller which are separately installed on both sides of a frame. A high-elasticity sponge (35), a urethane, or a rubber plate is adhered on the upper end of the deck board by a double sided tape (31a) to prevent transmission of impact to a user's knee, and to improve absorption of impact and a recovery ability. The high-elasticity sponge comprises: 28wt% of natural rubber, 26wt% of calcium carbonate, 20wt% of EVA, 8wt% of PE, 9wt% of a foaming agent, 4wt% of stearic acid, 2wt% of a cross-linking agent, 2wt% of zinc oxide, and 1wt% of pigment.
