A snow sliding apparatus enabling sliding on the snow surface comprising: a body in a flat shape that is extended in one direction, a nose and a tail that are bent and extended from both ends of the body in a direction that is away from a ground surface, and a first concavo-convex part that is formed in a way that one end of the nose or the tail converges into the inner side, wherein the body, the nose, the tail and the first concavo-convex part come in one piece made of metal, wherein the body is 1.0 cm ∼ 2.5 cm thick and 40 cm ∼ 70 cm long from the nose to the tail, wherein the first concavo-convex part comprises: a convergence portion where part of the nose or the tail converges, and a projected portion that is relatively protruded on both ends of the convergence portion, wherein a projected rail is protruded upwards on the top sides of the body, the nose and the tail, wherein a binding hole is formed on the projected rail for coupling with a binding, and wherein one part of the projected rail is extended to the projected portion of the first concavo-convex part, wherein the height from the ground to the bent end of the nose or the tail is 1.0 cm ∼ 4.0 cm, wherein a plurality of binding holes are formed along the projected rail, wherein at least one side of both sides of the body that is connected to the nose and the tail has a second concavo-convex part that converges into the inside and the second concavo-convex part takes the form of the circular arc of a virtual circle with the radius of 30cm∼80cm or takes a polygonal shape, wherein a dummy spacer is selectively combined with the first concavo-convex part to fill the convergence portion, and wherein the dummy spacer and the first concavo-convex part are coupled by a corresponding coupling piece and coupling slit that are relatively formed in the inner side of the dummy spacer and the first concavo-convex part, or the dummy spacer and the first concavo-convex part are coupled by a fastener. a body in a flat shape that is extended in one direction, a nose and a tail that are bent and extended from both ends of the body in a direction that is away from a ground surface, and a first concavo-convex part that is formed in a way that one end of the nose or the tail converges into the inner side, wherein the body, the nose, the tail and the first concavo-convex part come in one piece made of metal, wherein the body is 1.0 cm ∼ 2.5 cm thick and 40 cm ∼ 70 cm long from the nose to the tail, wherein the first concavo-convex part comprises: a convergence portion where part of the nose or the tail converges, and a projected portion that is relatively protruded on both ends of the convergence portion, wherein a projected rail is protruded upwards on the top sides of the body, the nose and the tail, a convergence portion where part of the nose or the tail converges, and a projected portion that is relatively protruded on both ends of the convergence portion, wherein a projected rail is protruded upwards on the top sides of the body, the nose and the tail, wherein a binding hole is formed on the projected rail for coupling with a binding, and wherein one part of the projected rail is extended to the projected portion of the first concavo-convex part, wherein the height from the ground to the bent end of the nose or the tail is 1.0 cm ∼ 4.0 cm, wherein a plurality of binding holes are formed along the projected rail, wherein at least one side of both sides of the body that is connected to the nose and the tail has a second concavo-convex part that converges into the inside and the second concavo-convex part takes the form of the circular arc of a virtual circle with the radius of 30cm∼80cm or takes a polygonal shape, wherein a dummy spacer is selectively combined with the first concavo-convex part to fill the convergence portion, and wherein the dummy spacer and the first concavo-convex part are coupled by a corresponding coupling piece and coupling slit that are relatively formed in the inner side of the dummy spacer and the first concavo-convex part, or the dummy spacer and the first concavo-convex part are coupled by a fastener.
