| 1. A vehicle stabilizer for high stress that is formed by conducting a hot-bending process on a solid round steel bar material,
wherein a bending portion is formed in a state which satisfies conditions:
0<φ≤4 and (φ×d/R)≤2,
in which d represents a material diameter of the solid round steel bar material, R represents a radius of bending of the bending
portion, d1 represents a short axis dimension of a cross section of the bending portion, d2 represents a long axis dimension of the cross section of the bending portion, and a flat rate φ of the cross section of the
bending portion is represented by the following equation:
φ=(d2−d1)/d2×100.
