To improve curving performances by facilitating the angling of ski boards without increasing the height of a plate.

The ski plate 1 which is interposed between the ski board and a binding and has a binding mounting part 5 is so arranged as to make a binding mounting position center 3 eccentric with respect to the ski board center 2. The binding mounting position center 3 is made eccentric inside the ski product. Otherwise, the degree S of eccentricity of the binding mounting position center 3 may be different before and after the plate or the plate 1 may be mounted on the existing charger plate mounting on the ski board. In this case, 3 mm to 5 mm is ideal in the degree S of eccentricity of the binding mounting position center 3 with respect to the ski board center 2.
