In the present invention, a substrate in which an innumerable number of dead skin cells are formed through a semiconductor etching technique is attached to the body, and a handle is provided on the body so that dead skin cells can be removed without directly holding the substrate. It relates to a sole exfoliator in which the substrates on which the protrusions of the array are formed can be respectively disposed to perform coarse grinding and smooth grinding, and each substrate is covered with a separate cover and is UV sterilized. To this end, in the present invention, a plurality of protrusions are formed on a glass substrate through etching, and these protrusions form an acute angle (α) on the upper surface and the side surface so that the keratin of the sole is cut at the corner of the upper surface； The substrate is a foot exfoliator fitted and fixed to a body having a handle, wherein the substrate comprises a first substrate for grinding coarse dead skin cells and a second substrate for grinding soft dead skin cells； The body is fixed by inserting the first substrate on an upper surface, and fixing the second substrate on a lower surface thereof, and a pair of body hinges are provided above and below on one side of the body； A first cover is rotatably connected to the upper body hinge portion with a hinge pin to close the first substrate, and is rotatably connected to the lower body hinge portion with a hinge pin to close the second substrate. 2 covers are provided, wherein the first cover and the second cover serve as a handle capable of grasping at the same time when the opposite surfaces contact each other in the unfolded state； When the first cover and the second cover are closed, a UVC LED that irradiates ultraviolet rays toward the first and second substrates is provided on an inner surface thereof.본 발명은 각질 제거용 돌기가 반도체 에칭 기법을 통하여 무수히 많이 형성된 기판이 몸체에 부착되고, 몸체에는 손잡이가 구비되어서 기판을 직접 잡지 않고 각질을 제거할 수 있도록 하였으며, 특히 몸체의 위아래 양면에는 서로다른 배열의 돌기들이 형성된 기판을 각각 배치하여 거친연삭 및
