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.
