To make easily performable deceleration timely by curving the main body of a snowboard upward in the range toward a rear end starting from a portion where the load of the rear foot is applied in the basic posture for sliding to form a bottom face portion kept in no contact with the snow surface, and fitting an antiskid material to the bottom face portion kept in no contact with the snow surface.

The main body 1 of a snowboard is curved upward in the range toward a rear end 5 starting from a portion where the load of the rear foot is applied when a rider stands with both feet faced laterally with respect to the tip 8 and uniformly applies the body weight in the basic posture for sliding, and a portion kept in no contact with the snow surface is formed as a deceleration face 6. The whole deceleration face 6 is scraped to form a fitting portion of an antiskid material 7, then the antiskid material 7 formed with a raw material such as urethane, rubber or a plastic into a mesh shape or a frictional shape in an irregular layout is fitted to the deceleration face 6. A footstool for the rear foot to be mounted with the rear foot for assuming the basic posture is fitted at the fitting portion of a rear foot boot binding on the upper face of the main body 1 of the snowboard.
