To provide a reinforcement member for a vehicle and a center pillar for a vehicle having the same, which can reduce the amount of spring back upon the pressing, and improve accuracy in a surface position.SOLUTION: There is provided an elongated reinforcement member for a vehicle, which has a U-shaped cross-section, which is disposed inside a structural member for a vehicle, and joined by welding. The reinforcement member for a vehicle comprises: a pair of reinforcement side vertical wall portions which extend in vertical and lateral directions of a vehicle so as to be opposed to each other, and which are disposed inside a pair of first vertical wall portions of the structural member for a vehicle, the first vertical wall portions being opposed to each other; and a reinforcement side connection wall portion that connects outside edges, in the lateral direction of the vehicle, of the pair of reinforcement side vertical wall portions. The pair of reinforcement side vertical wall portions includes pairs of protruding portions for welding, each of which protrudes outward in a longitudinal direction of the vehicle, over the whole width from each ridge line formed between the reinforcement side vertical wall portion and the reinforcement side connection wall portion, to an inside edge in the lateral direction of the vehicle. Each protruding portion for welding has a seating surface for welding, which is welded to the first vertical wall portion. The pairs of protruding portions for welding are disposed intermittently along the vertical direction of the vehicle.SELECTED DRAWING: Figure 4 【課題】プレス成形時のスプリングバック量を低減して、面位置精度の向上を図ることができる車両用補強部材、及びそれを備えた車両用センタピラーを提供する。【解決手段】車両用構造部材の内側に配置されて、溶接によって接合される断面コの字状で長尺状の車両用補強部材であって、互いに対向するように車両上下方向及び車幅方向に延び、前記車両用構造部材の相対向する一対の第１縦壁部の内側に配置される一対の補強側縦壁部と、一対の前記補強側縦壁部の車幅方向外側端縁を連結する補強側連結壁部と、を備え、一対の前記補強側縦壁部は、前記補強側連結壁部との間に形成される各稜線から車幅方向内側端縁までの全幅に渡って車両前後方向外側に突出して、前記第１縦壁部に溶接接合される溶接用座面が形成された一対の溶接用突出部を有し、一対の前記溶接用突出部は、車両上下方向に沿って間欠的に配置されるように構成する。【選択図】図４
