Abstract

Under compression by molds (), a wire (), a covered area (), and a crimping portion () are compressed and their cross-sectional areas decrease. Here, A1 is the cross-sectional area of the wire () after compression. That is, A1 is the sum of the cross-sectional area of the each strand after compression. Also,is the cross-sectional area of the covered area () after compression. In the present invention, the compression rate for the wire () is set between 50% and 80%. Also, the compression rate for the covered area () is set between 40% and 90%. The amount of compression by the molds () is set so that the compression rates are within these ranges. In the present invention, the compression rate is calculated by: (cross-sectional area after compression)/(cross-sectional area before compression). That is, 80% compression rate means that the cross-sectional area has decreased by 20% due to compression. That is, the relationships of 80%≥(A1/A0)≥50% and 90%≥(B1/B0)≥40% are satisfied.
