A platinum-based material element wire is coated with gold or gold alloy, and drawing-processed with a carbon-containing die. The thin wire manufactured in this manner is covered with gold or gold alloy, and the coverage of gold or gold alloy is 40% or more on an area basis. The thin wire formed of a platinum-based material is manufactured in a state of suppressing breakage in a drawing processing step, and has favorable performance in electric properties and the like. In addition, this manufacturing process is capable of efficiently manufacturing a platinum-based material thin wire while suppressing breakage when the thin wire is manufactured by drawing processing.
