PROBLEM TO BE SOLVED: To provide a conductor for high-frequency energization that is inexpensive and lightweight, has improved corrosion resistance and heat radiation properties, has low noise, and prevents dielectric breakdown from occurring easily.SOLUTION: In an aluminum conductor 10, an outer surface of an aluminum material 1 is covered with a film 2 constituted of a metal having electrical resistance higher than that of aluminum. The film 2 has a double-layer structure, and its outermost layer 4 is a tin-plated layer and an inner layer 5 disposed between the outermost layer 4 and the aluminum material 1 is a nickel-plated layer. The surface roughness Ra of the film 2 (outermost layer 4) exceeds 0.5 μm. |
