摘要:
A wire drawing die includes: a blank serving as a wear-resistant member provided with a die hole for performing a wire drawing process onto a wire material; and a die case that supports the blank. The blank has a thermal conductivity higher than a thermal conductivity of the die case. The blank has an upstream-side end surface and a downstream-side end surface in a wire drawing direction, the die hole is provided between the upstream-side end surface and the downstream-side end surface, and the downstream-side end surface is exposed from the die case.
