Abstract: The present invention relates to a plasma generating apparatus for a secondary battery. The plasma generating apparatus for the secondary battery comprises a transfer roller that transfers a separator, a metal member disposed within the transfer roller, a plasma generating member that interacts with the metal member to generate a plasma and irradiate the generated plasma onto a surface of the separator, and a protrusion member that causes a portion of the separator closely attached to the transfer roller to protrude and forms an adhesion area, which is adhesive, and a non-adhesion area, which is non-adhesive or less adhesive than the adhesion area, by allowing the plasma to be irradiated onto the adhesion area and no plasma or less plasma to be irradiated onto the non-adhesion area.
