The invention relates to a stylus manufacturing method for a contact probe, the stylus including a stick-shaped body, a stem formed continuous to an end of the body and having a diameter smaller than that of the body, and a tip formed continuous to an end of the stem and having a diameter larger than that of the stem. The method includes: primary electrical-discharge-machining of subjecting a leading end of a stick-shaped base material to electrical-discharge-machining to form the tip, a stem end being continuous to the tip and having the same diameter as the stem, and a temporary tapered portion having a diameter increasing from the stem end toward a base end of the base material; polishing of the tip formed in the primary electrical-discharge-machining; and after the polishing, secondary electrical-discharge-machining of subjecting the base material at least at the temporary tapered portion to electrical-discharge-machining to form the stem.
A method of manufacturing a stylus of a contact probe, the stylus comprising a stick-shaped body, a stem formed continuous to an end of the body and having a diameter smaller than a diameter of the body, and a tip formed continuous to an end of the stem and having a diameter larger than the diameter of the stem,
