摘要： A sterilization apparatus is disclosed. The sterilization apparatus includes: a main body; and a plurality of sterilization modules. The main body defines a sterilization space for sterilization of a sterilization target. The sterilization modules are disposed on a plurality of inner surfaces of the main body surrounding the sterilization space, respectively, and deliver germicidal light to the sterilization space. In addition, the sterilization module includes a support member and a plurality of light sources. The support member is mounted on the inner surface of the main body. In addition, the plurality of light sources is mounted on the support member and emits the germicidal light. Here, a space between adjacent light sources disposed in some regions of the support member is different from a space between adjacent light sources disposed in the other regions of the support member.
