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 configured to transfer a separator; a metal member built in the transfer roller; a plasma generating member configured to interact with the metal member to generate plasma and irradiate the generated plasma onto a surface of the separator; and a protrusion member configured to realize an adhesion area from which a portion of the separator closely attached to the transfer roller protrudes and onto which the plasma is irradiated to provide adhesion and a non-adhesion area onto which the plasma is not irradiated or is weakly irradiated when compared with the adhesion area so that there is no adhesion or the resulting adhesion is weaker than that of the adhesion area.
