A sheet-like fiber structure including a plurality of fibers made of amorphous silicon dioxide. The plurality of fibers are intertwined with each other and thus connected to each other, thereby forming void portions. Consequently, the sheet-like fiber structure has not only liquid permeability and voltage resistance but also high heat resistance and chemical resistance. The sheet-like fiber structure is therefore applicable to a separator for preventing a short circuit between electrodes, a scaffold for cell culture, to holding a biomolecule, or the like.
