To provide a reinforcement member comprising a core cord layer and a spiral cord layer arranged outside of the core cord layer which can suppress breaking of a reinforcement cord due to fretting (friction) between a core cord and the reinforcement cord, and a tire improving a tire life using the same.SOLUTION: A reinforcement member 1 comprises a core cord layer 2 including at least one layer; and a spiral cord layer 3 including a reinforcement cord 3a spirally wound around the core cord layer 2, where a core cord 2a constituting the core cord layer 2 is slanted against a longer direction of the reinforcement member 1, and an edge face of the core cord 2a at an end part of the reinforcement member 1 in the width direction is corner-cut, and a tire is given using the same.SELECTED DRAWING: Figure 2B

    【課題】芯材コード層と、その外側に配置された螺旋状コード層と、を有する補強部材における、芯材コードと補強コードとのフレッティング(擦れ合い)に起因する補強コードの破断を抑制することのできる補強部材、および、それを用いることで、タイヤ寿命を向上したタイヤを提供する。【解決手段】少なくとも1層の芯材コード層2と、芯材コード層2に螺旋状に巻き付けられた補強コード3aを含む螺旋状コード層3と、を有し、芯材コード層2を構成する芯材コード2aが、補強部材1の長手方向に対し傾斜しており、かつ、補強部材1の幅方向端部における芯材コード2aの端面が、角取りされてなる補強部材1、および、それを用いたタイヤである。【選択図】図2B
