A method for manufacturing a high frequency cable that includes covering a central conductor made from aluminum or an aluminum alloy with a covering layer made from copper; and wire drawing of the central conductor covered by the covering layer using dies at multiple steps, each of the dies having a cross-section reduction rate of 20% to 29% with an entire reduction angle of 16 degrees, to form a fiber-like structure in a longitudinal direction in the covering layer, and to form an intermetallic compound layer having greater volume resistivity than the covering layer between the central conductor and the covering layer.

High frequency cable, high frequency coil and method for manufacturing high frequency cable

A high frequency cable includes: a central conductor made from aluminum or an aluminum alloy; a covering layer made from copper covering the central conductor, and having a fiber-like structure in a longitudinal direction; and an intermetallic compound layer formed between the central conductor and the covering layer and having greater volume resistivity than the covering layer, wherein a cross-sectional area of the covering layer is 15% or less of an entire cross-sectional area including the central conductor, the intermetallic compound layer and the covering layer.
