A diamond-like carbon (DLC) film is formed on a portion of a reed blade in a high-speed loom which requires the highest wear resistance. When a stainless steel is used as the base material of the reed blade, the DLC film is formed through an intermediate layer comprising, e.g., a titanium carbide layer. Reed blades coated with a DLC film are arranged at the side portions of the reed where wear progresses quickly, while reed blades coated with hard films requiring a relatively low cost, or non-coated reed blades, are arranged in the central portion of the reed, thereby uniforming the blade wear throughout the entire reed. The reed is suitable to many types of fibers, ranging from natural to synthetic and new material fibers.
