PROBLEM TO BE SOLVED: To provide a composite yarn in a monofilament state, applicable to reinforcement material and the like, and having high strength, high flexibility, and excellent handleability.SOLUTION: There is provided a composite yarn in a monofilament state in which an entire outer periphery of a bundle of continuous reinforcement fiber as multifilament is coated with a thermoplastic resin. The ratio of the tensile strength of the continuous reinforcement fiber in the composite yarn in the composite yarn state to the tensile strength of the continuous reinforcement fiber measured in a state that the thermoplastic resin is removed from the composite yarn, is 99 to 104%.SELECTED DRAWING: NoneCOPYRIGHT: (C)2020,JPO&INPIT【課題】補強材等に応用可能な高強度、高柔軟性、取り扱い性に優れたモノフィラメント状の複合糸の提供。【解決手段】マルチフィラメントである連続強化繊維の束の外周全体が熱可塑性樹脂により被覆されているモノフィラメント状の複合糸であって、該複合糸状態での複合糸中の連続強化繊維の引張強度が、複合糸から熱可塑性樹脂を除去した状態で測定した連続強化繊維の引張強度に対して９９～１０４％である複合糸。【選択図】なし
