To provide a shoe dryer efficiently performing drying, deodorization, and sterilization of a shoe, and not damaging the shoe.

This shoe dryer 1 includes: storage means storing the shoe S; ozone supply means supplying air containing ozone to the shoe S; heating means supplying heated air to the shoe S; and cooling means supplying cooled air to the shoe S. A controller performs control to achieve an optimized temperature and time of the supply of the air when supplying the air by the means. As a result, the shoe S can be efficiently performed with drying, deodorization, and sterilization treatment in a state that the shoe S is not damaged. By using ultraviolet irradiation means or coating the inner surface of the storage means with photocatalyst titanium oxide, deodorization and sterilization effect in the shoe S, a peripheral area of the shoe S, and the inner surface of the storage means can be promoted.
