The present invention relates to a plasma sterilization module, comprising: a housing which is disposed on a flow path through which air flows, and having a first surface through which the air is introduced and a second surface, opposite to the first surface, through which the introduced air is discharged; a discharge electrode disposed in the housing; and a ground electrode disposed in the housing and spaced apart from the discharge electrode, wherein the discharge electrode is applied with a high voltage to generate a plasma discharge toward the ground electrode between the first surface and the second surface, and the discharge electrode and the ground electrode are disposed so as to allow air introduced into the first surface to directly pass through an area wherein the plasma discharge occurs, and be discharged to the second surface, thereby sterilizing microbes in the air.

A sterilization device includes: a frame having a first surface into which air flows, and a second surface from which air flows out; one or more discharge electrodes disposed in the frame; and a plurality of ground electrodes alternately arranged with the discharge electrodes. The discharge electrodes each comprise: a framework extending in the direction parallel to the ground electrodes; a first discharge needle protruding toward the first surface from the framework; and a second discharge needle protruding toward the second surface from the framework. The discharge electrodes are inclined at a predetermined angle with respect to an arbitrary axis of rotation parallel to the direction in which the ground electrodes extend, such that a discharge treatment region is formed perpendicularly to a flow direction by means of the alternate arrangement of the discharge electrodes and the ground electrodes parallel to the flow direction.
