Provided are frame members from which a structure can be efficiently assembled, and a structure using the frame members. On a surface of a vertical frame member 28, there are printed a position identification mark (sectional shape mark) showing the position where a horizontal frame member 34 is to be butted, a nut position identification mark N showing the mounting position of a nut 46 which is to be inserted into a guide groove 22, and a position identification mark showing the mounting position of a bracket 42. The frame members can be efficiently assembled to manufacture a structure, without referring to a drawing for assembly.
