Joined conductor, conductor joining device, method for manufacturing joined conductor, and conductor joining method

Abstract

[Object] The present invention provides a joined conductor and a method for manufacturing a joined conductor that can improve electrical conductivity between conductors. [Solution] In a joined conductorincluding a joining portionin which a plurality of conductors exposed portionsarranged along a longitudinal direction X are fused and joined, the joining portionis configured to have a substantially rectangular shape in an orthogonal cross section orthogonal to the longitudinal direction X, and among a pair of side surfaces in width directionand a pair of side surfaces in up-down directionconfigured such that a first surfaceand a second surfacethat face each other in the orthogonal cross section, and a hornand a hornare paired, on each of the first surfaceand the second surfaceof the pair of side surfaces in width directionthat are at least one pair, a corrugated portionthat has a corrugated shape and in which a ridgeprotruding outward and a valleyrecessed inward are alternately continuously provided along the longitudinal direction X is formed.
