Abstract: In a structure 21 for connecting an electric wire and a connecting terminal in the invention, a ductile metal film 29 is formed in advance on an inner surface of a conductor caulking portion 24 of a crimp terminal 22 by such as plating, vacuum deposition, or adhesion.

Hence, the area of contact between the conductor caulking portion 24 and the core wire portions M via the metal film 29 increases, and conductivity improves, thereby making it possible to suppress heat generation.
