PURPOSE:To provide a titled wire which has adequate flexibility, is reduced in weight and is improved in tensile strength by forming the wire of a wire- shaped composite structure which consists of PE fibers having specific tensile strength and tensile modulus as a reinforcing material and a thermosetting resin as a matrix material and has specific bending modulus. CONSTITUTION:The PE fibers (A) has the tensile strength of at least 20g/denier, more preferably >=30g/denier and more particularly preferably >=40g/denier and the tensile modulus of at least 500g/denier, more preferably >=800g/denier and more particularly preferably >=1,000g/denier. The thermosetting resin (B) is an unsatd. polyester resin, vinyl ester resin, epoxy resin, phenolic resin, etc. which are used alone or the compd. of >=2 kinds. The bending modulus of the wire-shaped composite body constituted of (A) and (B) is 300-1,500kg/mm<2>, more preferably 500-1,000kg/mm<2>, the tensile break strength thereof is at least 40kg/mm<2>, more preferably >=60kg/mm<2> and the fiber content (Vf) thereof is 15-60%, more preferably 20-50%.
