PROBLEM TO BE SOLVED: To provide components of extrusion material, capable of easily forming a closed section having a hollow part into a desired shape in a direction where the hollow part extends, and to provide a method for manufacturing the same. SOLUTION: A brace 10 is made, such that a base member 16 is made by dividing a first extrusion member 21 where a section 22 having a hollow part 23 is continuous in a specified shape in an extruding direction F, while holding the section 22. As a second step, a second extruded member 50, where a section 51 having a hollow part 52 is continuous in a specified shape in an extruding direction F, is divided in such a way that the section 51 becomes an irregular shape in the extruding direction F, to form a couple at the hollow part 52. With such a processing as above, there is formed a sub-member 20 where a connecting surface 64, formed through the dividing operation, is fixed to a right wall 41 of the base member 16 so as to form a closed section. As a third step, the connecting surface 64 of the sub-member 20 is connected to the right wall 41 of the base member 16. The brace 10 is formed through the first step to the third step.
