PROBLEM TO BE SOLVED: To provide a method of manufacturing a crimp terminal that is excellent in dimensional precision.SOLUTION: A method of manufacturing a crimp terminal 10 that has a cylindrical crimp portion 20 at one end thereof and has a plate-like connection portion 30 at the other end thereof comprises a first step S20 for forming a cavity 51 having a bottom at one end 501 of a columnar member 50, a second step S30 for forming a groove 52 at a position nearer to the other end 502 side than the cavity 51 in the columnar member 50, and a third step S40 for rolling a portion nearer to the other end 502 side than the groove 52 in the columnar portion 50. The cavity 51 extends along the axial direction of the columnar member 50, and the groove 52 extends along a direction intersecting to the axial direction of the columnar member 50.SELECTED DRAWING: Figure 3 【課題】寸法精度に優れた圧着端子の製造方法を提供する。【解決手段】筒状の圧着部２０を一端に有すると共に、板状の接続部３０を他端に有する圧着端子１０の製造方法は、柱状部材５０の一端５０１に有底の穴５１を形成する第１の工程Ｓ２０と、柱状部材５０において穴５１よりも他端５０２側に溝５２を形成する第２の工程Ｓ３０と、柱状部分５０において溝５２よりも他端５０２側の部分を圧延する第３の工程Ｓ４０と、を備えており、穴５１は、柱状部材５０の軸方向に沿って延在し、溝５２は、柱状部材５０の軸方向に交差する方向に沿って延在する。【選択図】 図３
