  • an electrical connection portion provided at a front of the crimp terminal in a terminal longitudinal direction; and

    a conductor crimping portion that is provided closer to a rear than the electrical connection portion in the terminal longitudinal direction, and is crimped and connected to a conductor of a terminal of an electrical wire,whereinthe conductor crimping portion is formed to have a substantially U-letter shaped cross section,the conductor crimping portion has a bottom plate, and a pair of conductor crimping pieces that are extended upward from both left and right side edges of the bottom plate and that crimp the conductor of the electrical wire arranged on an inner surface of the bottom plate so as to wrap the conductor of the electrical wire,concave serrations are provided in an inner surface of the conductor crimping portion,a number of circular concave portions are provided in the inner surface of the conductor crimping portion as the concave serrations so as to be scattered in a state of being spaced aside from one another, in a state before the conductor crimping portion is crimped to the conductor of the electrical wire,a diameter of an inner bottom surface of each circular concave portion is set within a range of 0.15 (the error range is ±

    0.04) mm to 0.8 (the error range is ±

    0.04) mm,a serration angle between an extension surface of the inner bottom surface and an inner side surface of the each circular concave portion is set within a range of 60 to 90 degrees, anda shortest distance of a flat surface portion between peripheries of mutually adjacent circular concave portions is set to be 0.17 (the error range is ±

    0.09) mm.
