Herein, to produce the column, the composite material is accumulated on a reinforced part of the column. The column is covered by a vacuum bag and put in an autoclave. The composite material is hardened by giving pressure outside while keeping a vacuum state in the inside. Accordingly, the column reinforced by the composite material is produced.
