To provide a disc brake capable of suppressing fine abrasion powder from being scattered into the atmosphere.SOLUTION: A brake disc 10 is manufactured in a disc shape through a plurality of steps including a casting step. The brake disc 10 has a casting surface formed in the casting step on a first sliding surface 11o and a second sliding surface 11i that are in contact with a brake pad 21, and is formed with a groove 13 extending in a radial direction. Also, when the brake disc 10 is a ventilated type, a hole 14 is formed on the first sliding surface 11o and the second sliding surface 11i so as to communicate with a ventilation passage 11d having the casting surface formed in the casting step.SELECTED DRAWING: Figure 1

    【課題】微細な摩耗粉の大気中への飛散を抑制することができるブレーキディスクを提供すること。【解決手段】ブレーキディスク10は、鋳造工程を含む複数の工程を経て円盤状に製造される。ブレーキディスク10は、ブレーキパッド21と接触する第一摺動面11o及び第二摺動面11iに、鋳造工程にて形成された鋳肌面を有し、且つ、径方向に延設された溝部13が形成される。又、ブレーキディスク10がベンチレーティッド型の場合には、第一摺動面11o及び第二摺動面11iに、鋳造工程にて形成された鋳肌面を有する通気路11dに連通する孔部14が形成される。【選択図】図1
