Abstract
An audio/video cable includes an insulated layer including a copper conductor for transmitting audio/video signals and an insulation layer formed on a periphery thereof. The copper conductor includes a soft dilute copper alloy material containing pure copper, Ti as an additive element and an inevitable impurity as a balance. The soft dilute copper alloy material includes a recrystallized structure having a grain size distribution such that crystal grains in a surface layer are smaller than internal crystal grains. The soft dilute copper alloy material includes not less than 2 and not more than 12 mass ppm of sulfur, more than 2 mass ppm but not more than 30 mass ppm of oxygen, and not less than 4 and not more than 55 mass ppm of Ti.
