To secure in-plane rigidity of a resin-coated cord and in-plane rigidity of a member formed from the resin-coated cord.SOLUTION: A resin-coated cord 42 comprises n-cords (reinforcement cords 44) that are arranged at mutual intervals, a coating resin 46B for coating the cord, and an adhesive resin 46A that is arranged between the cord and the coating resin 46B and the tensile modulus of elasticity of which is greater than that of the coating resin 46B. When A represents a total value of a width-direction dimension of a part in which the cord and the adhesive resin 46A are arranged and B represents a maximum value of a thickness-direction dimension, the resin-coated cord satisfies the following inequality (1): B<(A/n) (n≥1).SELECTED DRAWING: Figure 3
【課題】樹脂被覆コードの面内剛性及び樹脂被覆コードによって形成される部材の面内剛性を確保する。【解決手段】樹脂被覆コード42は、互いに間隔を空けて配置されたn本のコード(補強コード44)と、コードを被覆する被覆樹脂46Bと、コードと被覆樹脂46Bとの間に配置され、被覆樹脂46Bより引張弾性率が大きい接着樹脂46Aと、を備え、コード及び接着樹脂46Aが配置された部分の幅方向寸法の合計値をAとし、厚み方向寸法の最大値をBとした時に、次の(1)式を満たす。 B<(A/n) (n≧1)・・・(1)【選択図】図3
