To provide a covering yarn in which fuzz in processing is suppressed and which is excellent in productivity in processing and a method for producing a covering yarn and a method for producing a molded article.SOLUTION: A covering yarn includes a continuous reinforced fiber, a combined filament yarn 11 comprising a first continuous thermoplastic resin fiber, and a second continuous thermoplastic resin fiber 12 wound around the combined filament yarn 11 spirally in the longitudinal direction. The second continuous thermoplastic resin fiber 12 is wound around the combined filament yarn 11 spirally at a pitch of 0.5-10 mm and at an angle of 20-80°.SELECTED DRAWING: Figure 1 【課題】加工時の毛羽立ちが抑制され、かつ、加工時の生産性に優れたカバリング糸、カバリング糸の製造方法および成形品の製造方法の提供。【解決手段】連続強化繊維と、第一の連続熱可塑性樹脂繊維を含む混繊糸１１と、混繊糸１１の長手方向にらせん状に巻き付いている第二の連続熱可塑性樹脂繊維１２とを有し、第二の連続熱可塑性樹脂繊維１２は、混繊糸１１に０．５〜１０ｍｍのピッチ、かつ、２０〜８０°の角度でらせん状に巻き付いている、カバリング糸。【選択図】図１
