Abstract: A discharge electrode E in an electrode chamber C is formed of a pair of electrode members 8 and 9 having lengths equal to or greater than a width of a film F. Also, the pair of electrode members 8 and 9 are disposed facing each other so as to sandwich a support member 4 there-between, which has nearly the same length as to electrode members; a gap is formed in a section in which the pair of electrode members 8 and 9 face each other; and this gap is open at a tip of the discharge electrode so as to serve as a gas pathway 15. Meanwhile, in the aforementioned support member 4, a plurality of gas guiding holes 5 are formed in a longitudinal direction thereof, and the gas guiding holes are in communication with a gas supplying system.

Abstract: A discharge electrode E in an electrode chamber C comprises a plurality of electrode members 8, 9. The electrode members 8, 9 are disposed facing each other by having a supporting member 4 therebetween, a gap is formed between the facing portions of the electrode members 8, 9, and by having the gap as a gas passageway 15, the gas passageway is opened in the leading end of the discharge electrode. A replacement gas having been supplied from a manifold pipe 3 is supplied to the gas passageway 15 via an orifice.

Abstract: Surface modification device forms a discharge area E1 between a discharge electrode 6 and a counter electrode 4, supplies substitution gas to the discharge area E1, and modifies the surface of the base material to be processed. The surface modification device comprises; a slit-shaped substitution gas passage; and cover members 7, 8 that form curtain passages 22, 23 in spaces facing the discharge electrode. While the substitution gas is being supplied to the discharge area E1, gas injected from the curtain passages 22, 23 prevent the inflow of an entrained flow a and the outflows b1, b2 of the substitution gas, thereby maintaining the concentration of substitution gas inside the discharge area E1.
