PROBLEM TO BE SOLVED: To provide, in a plasma-discharge treatment of a long support transported at a high speed in a gas at atmospheric pressure or its vicinity, a completely novel surface treatment unit of a support capable of enhancing adhesion of a nonadhesive material and improving its quality, by almost completely preventing the mixture of accompanying air into a treating room whereby improving treatment efficiency, a surface treatment method of the support which is treated using the unit, and a surface treated support treated using the method. SOLUTION: This surface treatment unit of a support has a treatment room 12 where the surface of a support 15 is plasma-discharge treated while it is continuously transported in an inert gas contg. not less than 50% argon gas at atmospheric pressure, or its vicinity, and auxiliary rooms 13a-1, 2 at least 2 at the support entrance side of the treatment room or at least 2 each at both entrance and exit. |
