To provide a manufacturing method of a terminal-equipped wire and a terminal-equipped wire that can effectively suppress the disconnection of a metal wire constituting a conductor of the wire.SOLUTION: A manufacturing method of a terminal-equipped wire according to the present invention includes steps of: peeling off an insulating coating 5 to expose a part of a conductor 4; sandwiching the exposed part 4a of the conductor 4 between the pressure surfaces 22 by using a pair of vibrators 21 each having a semicircular first pressure surface 22, applying ultrasonic vibration to the exposed part 4a of the conductor 4 by the pair of vibrators 21 in that state in a direction orthogonal to the pressure applied direction by the pair of vibrators 21 to join metal wires constituting the conductor 4 while maintaining the cross-sectional shape of the exposed part 4a of the conductor 4 in a circular shape; and sandwiching a plurality of locations of the tubular portion 8 in the second pressing surfaces 26 by using a pair of compression dies 25 each having a multi-faceted second pressing surface 26 with a joint portion 4a of the conductor 4 inserted into the tubular portion 8 to connect the tubular portion 8 to the joint portion 4a of the conductor 4 at a plurality of locations.SELECTED DRAWING: Figure 3 【課題】電線の導体を構成している金属素線の断線を効果的に抑制することができる端子付き電線の製造方法及び端子付き電線を提供する。【解決手段】本発明の端子付き電線の製造方法は、絶縁被覆５を剥がして導体４の一部を露出させる工程と、それぞれ半円形の第１加圧面２２を有する一対の振動子２１を用いて導体４の露出部４ａを加圧面２２で挟み込み、その状態で一対の振動子２１により導体４の露出部４ａに超音波振動を一対の振動子２１による圧力の印加方向と直交する方向に加えることにより、導体４の露出部４ａの断面形状が円形に維持された状態で導体４を構成する金属素線どうしを接合する工程と、導体４の接合部４ａを筒部８内に挿入した状態で、それぞれ多面形の第２加圧面２６を有する一対の圧縮ダイス２５を用いて筒部８の複数箇所それぞれを第２加圧面２６で挟み込むことにより、導体４の接合部４ａに筒部８を複数箇所において接続する工程と、を含む。【選択図】図３
