PROBLEM TO BE SOLVED: To achieve reliable electric connection and improvement of mechanical strength at a low cost in crimp connection between a wire and a connecting terminal using a common tool without special configuration for a connecting terminal. SOLUTION: The connecting terminal 10 includes, for example, a connecting portion 11, a crimp barrel portion 12, and a holding barrel portion 13, and an aluminum electric wire 20 has a structure in which a core wire 21 is covered with a coating 22. The aluminum electric wire 20 is crimped and held on the connecting terminal 10 at the holding barrel portion 13 with the coating 22, and crimped by a crimped portion 23 at the crimp barrel portion 12 to conduct electricity. The crimped portion 23 has a configuration in which an end portion of the core wire 21 is folded one time, for example, wherein a radius R2 of the core wire on the end side is larger than a radius R1 of the core wire on a base end side. Thus, the core wire 21 is reliably and strictly crimped by the crimp barrel portion 12 using common tool without special terminal configuration, which achieves crimp connection at a low cost.
