A plasma generation apparatus and method, which achieve both sterilization and deodorization of attached bacteria even under the condition that steam or fine droplets of water are present. A pair of electrodes is prepared, 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 steam or fine droplets of water are applied to the fluid passage holes and plasma generated around the fluid passage holes.
