Abstract
[Problem] To provide a bent product from an integrally extrusion molded body without the loss of lightweight properties or the like. [Solution] A bent product (10) that is formed by bending an integrally extrusion-formed body and has: a metal core material (20) provided with a tube-shaped peripheral wall (21) and a first partition wall (23) that extends in the longitudinal direction of the tube shape and divides the inner space of the peripheral wall in the direction of the major axis of the cross section perpendicular to the longitudinal direction of the tube shape; and a covering layer (40) that is formed on the outer surface of the core material and contains at least a thermoplastic resin. The thickness (t) of the peripheral wall is 0.8-2.3 mm, and a reinforcing means is provided to the inner space side of the peripheral wall at a section (25) thereof to the inside of the bend.
