ABSTRACT:
Manufacturing of a sipe blade at a low cost and in a short time, and shortening of a manufacturing period and reduction in cost of a tire vulcanizing mold are achieved. A metal wire material is subjected to rolling and molding processing, and subsequently is subjected to heat treatment to form an intermediate material. The intermediate material is cut off and a hole is formed therein, and the sipe blade is thereby manufactured.
