Disclosed is a tread kerf (100) of a snow tire which easily discharges snow trapped in the kerf. The tread kerf (100) is formed on an outer surface of a block of a tread of the snow tire and has a trapezoidal wave structure (W1) extending along the surface and formed in a depth direction of the block, and an amplitude of the trapezoidal wave structure is gradually decreased in a direction from a tire surface (S1) to a tire base (S2). Since the amplitude of the tread kerf is gradually decreased in the direction from the tire surface to the tire base, the tread kerf may easily discharge snow trapped in the kerf to the outside of the tire block through the tire surface, even if a small space formed by the kerf is filled with snow when the tire is rotated on a snowy road.
