<p>Before a conductive crimp part (11) is crimped to a conductor (Wa) of an electric wire, a plurality of circular concave parts (20) are provided in an inner surface (11R) of the conductive crimp part (11) at positions spaced apart from each other to serve as serrations of the conductive crimp part (11). The inner bottom surfaces (20A) of the concave portions (20) have semispherical surfaces.</p>
