The present invention relates to a cutting board sterilizing and drying apparatus. According to the present invention, the cutting board sterilizing and drying apparatus comprises: a housing which has a cutting board insertion hole formed in the front of the housing, a cutting board receiving space formed in the housing, and transparent windows formed on both sides of the housing to allow the cutting board receiving space to be visible； an ultraviolet lamp formed on the upper part of the cutting board receiving space； and multiple air blowing fans upwardly and downwardly formed on the back side of the housing. The bottom surface of the cutting board receiving space is formed to have a fixed inclination so that the front part of the bottom surface is higher than the back part of the bottom surface. A rear stopper is formed on the back side of the cutting board receiving space facing the cutting board insertion hole. The rear stopper is separated at a regular interval from the back side of the housing, is perpendicular to the bottom surface, and has a plurality of holes to allow air to flow into the cutting board receiving space by the multiple air blowing fans. Furthermore, a pair of cutting board holders are formed on both sides of the cutting board receiving space in order to minimize the movement of the cutting board being inserted and hold the cutting board, and the pair of cutting board holders are made from elastic materials and are separately attached to both inner sides of the housing to protrude. According to the present invention, the cutting board sterilizing and drying apparatus has the advantages of being formed in a compact size, having a structure easy to insert the cutting board or take out the same, and having good mounting ability. In addition, the cutting board sterilizing and drying apparatus has the advantage of minimizing the breakage of the cutting board or the damage of the cutting board receiving space when a user inserts the cutting board or
