To provide a friction material which enables a user to grasp a degree of wear without putting effort into it.SOLUTION: A friction material 100 of an embodiment is pressed against a wheel provided at a railway vehicle to brake the railway vehicle. In the friction material 100, two holes 110A, 110B are formed between a friction surface 101 which is pressed against the wheel to rub and a rear surface 102 opposite to the friction surface 101. Positions and numbers of the holes 110A, 110B exposed on the friction surface 101 change as abrasion of the friction surface 101 proceeds toward the rear surface 102.SELECTED DRAWING: Figure 4

    【課題】手間をかけることなく、摩耗の程度を容易に把握することができる摩擦材を提供する。【解決手段】実施形態の摩擦材100は、鉄道車両が有する車輪に押し付けられて鉄道車両を制動する摩擦材100である。摩擦材100には、車輪に押し付けられて摩擦する摩擦面101と摩擦面101とは反対側の裏面102との間に2つの穴110A,110Bが形成されている。摩擦面101に露出している穴110A,110Bの位置及び数は、摩擦面101の摩耗が裏面102に向かって進むに従って変化する。【選択図】図4
