摘要： An enameled flat wire includes a flat wire and an enamel coating. The difference in thickness of the enamel coating on flat surfaces between a maximum thickness and a minimum thickness is equal to or less than 25% of the predetermined thickness. The enamel coating prior to baking includes a maximum surface curvature on each of the rounded corners of the wire, and a depression on at least one of the flat surfaces of the wire, the depression has a maximum surface curvature. The maximum surface curvature of the depression is larger than the maximum surface curvature of the enamel coating prior to baking on at least one of the rounded corners thereof.

摘要： 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.

摘要： A manufacturing method uses a solid coating die for applying an insulation varnish around a flat wire conductor. The die includes a die body and a die hole formed through the die body, into which the conductor is inserted. The die hole includes an entry portion having a cross section monotonically decreasing along a conductor insertion direction, and a coating portion including at least a sub-portion having a constant cross section. The cross section of the coating portion is a rectangle having four straight sides and four rounded corners. Each inner surface of each straight side has an inwardly projecting protrusion, a top contour of each protrusion being a circular arc, an elongated circular arc, an elliptical arc or a combination of these arcs, the maximum curvature of the top contour of each protrusion being larger than the maximum curvature of inner surface of the rounded corners.
