A joint of a copper terminal and an aluminum wire, the copper terminal is divided into a connecting part and a functional part connected to the connecting part, and an aluminum wire core of the aluminum wire is connected to the connecting part of the copper terminal. Preferably, the aluminum wire core extends or does not extend to the functional part. The connecting part is a component of the copper terminal that is connected with the aluminum wire, and the functional part is a fixed area of the copper terminal that is configured to connect to a power consumption device.

A connection assembly is provided and includes a first conductor, a second conductor and a friction stir welded connection connecting the first conductor and the second conductor, with the second conductor having a bundle of conductor wires. The friction stir welded connection is provided by a friction stir welding tool having a pin connecting a front side of the second conductor pressed onto the first conductor along a connecting direction between the first conductor and the second conductor.

An electric wire with a terminal includes: an electric wire having a core wire, and a cover; a crimp terminal having a core wire crimping portion which is crimped to the core wire, a cover crimping portion which is crimped to the cover, and a connecting portion which extends from the core crimping portion to the cover crimping portion; and a resin which integrally covers the core wire and the crimp terminal. The core wire has an intermediate portion which extends between the core crimping portion and the cover crimping portion. The connecting portion has a bottom wall portion and a pair of side wall portions which extend in a height direction of the crimp terminal from end portions of the bottom wall portion in a width direction.

A wire harness that includes a first wire and a second wire each including a core wire and a covering material that covers the core wire; and a tube, wherein: the tube covers a connection between the core wire of the first wire and the core wire of the second wire, each of the covering materials contains a cross-linked polyethylene, the tube contains a cross-linked polyethylene, the tube and each of the covering materials are directly joined, and a tensile shear strength between the tube and each of the covering materials is 350 kPa or more.
