Following the cylindrical bend processing of the shape crimping portion corresponding part corresponding to the crimping section in the sheet-shaped terminal base material, the high bending-rate processing process of bend processing at a bending rate higher than a bending rate for plastically deforming at least a part of a deformation portion to be plastically deformed in a predetermined bend processing shape in the crimping portion corresponding part, and the shaping process of shaping the crimping portion corresponding part into the cylindrical crimping section are performed in this order.

Manufacturing method of cylindrical body crimp terminal

A transition portion () has a surface () that is formed extending upward. The surface () is a surface formed extending upward so as to face a bottom portion (). Specifically, the transition portion () has a cross-sectional shape in which upper edge portions of side portions () are bent inward. As the surface () approaches a main terminal body () from a sealing portion (), the surface () gradually separates away from the bottom portion () and the edge portions of the surface () gradually open outward and connect to side portions () of the main terminal body (). The surface () is formed so as to be curved upward, in a cross-section, from the end portion of the sealing portion ().
