PROBLEM TO BE SOLVED : To provide a plasma-discharge treatment apparatus which continuously allows a uniform reforming treatment of the surfaces of wide base materials. SOLUTION : The plasma-discharge treatment apparatus includes a first electrode and a second electrode provided oppositely and treats the surface of a base material by allowing the base material to pass through a discharge part formed between the first and second electrodes. Further, the plasma-discharge treatment apparatus includes a power supply member arranged in no contact with the first electrode and an earth member arranged in no contact with the second electrode, wherein the first electrode is configured so as to be movable with respect to the power supply member and the second electrode is configured so as to be movable with respect to the earth member.
