Abstract
A method of manufacturing a functional hollow structural member having a structural member having a hollow part, and functional means disposed on the inside surface of the hollow part, comprising the steps of injecting a molding material into a molding die, injecting a gas and a functional substance into the molding material to form a hollow part in the molding material, forming functional means inside of the hollow part, and forming a structural member by solidifying the molding material. As the functional means, a layer having a magnetic function, conductive function, or antibacterial function is used.
