A deodorization and sterilization apparatus and method, which increases an amount of generated active species and collects floating bacteria or odor materials in air at one place, such that the active species make contact with the collected floating bacteria or odor materials to achieve high-efficiency sterilization and deodorization. A pair of electrodes is provided, plasma discharge is carried out by applying designated voltage between the pair of electrodes, fluid passage holes are provided at corresponding parts of respective electrodes so as to communicate with each other, and at least one absorption member to absorb floating bacteria or odor materials is disposed at the downstream of a fluid passing through the fluid passage holes.
