To obtain a vehicle body component that can stably maintain collision energy absorption performance even when a process mark formed by a multi-stage cutting process is formed on an outer edge.SOLUTION: A door impact beam 10 as a vehicle body component is formed in a long shape and has a body portion 11 having a hat shape. A pair of matchings 25 are provided at a right end edge 23 and a left end edge 24 of an outer edge of the door impact beam 10, respectively. In a manufacturing stage in which the door impact beam 10 is manufactured through a multi-stage punching process, the matching 25 is formed in a connecting portion 26 where a first cutting line in the former stage process and a second cutting line in the latter stage process intersect.SELECTED DRAWING: Figure 1

    【課題】複数段階の切断加工によって形成される加工痕が外縁部に形成されていても、衝突エネルギー吸収性能を安定的に維持することができる車体部品を得ること。【解決手段】車体部品であるドアインパクトビーム10は、長尺状をなすように形成され、ハット形状をなす本体部11を有している。ドアインパクトビーム10の外縁部のうち右端縁部23及び左端縁部24には、それぞれ一対のマッチング25が設けられている。マッチング25は、複数段階の打ち抜き加工を経てドアインパクトビーム10を製造する製造段階において、前段加工における第1切断ラインと後段加工における第2切断ラインとが交わるつなぎ部26に形成される。【選択図】 図1
