After a rod-like titanium material 20 is accommodated in a generally linear-shaped groove 13 of a first mold 7, a first guide portion 15 of a second mold 8 is fitted to the groove 13. Thereafter, the first mold 7 is moved along an arrow A direction relative to the second mold 8 fixed to an anchor block, by which the titanium material 20 substantially immovably retained in the groove 13 of the first mold 7 is bent and pushed into a through hole 24 of the second mold 8 by the first guide portion 15, thus being plastically deformed.
