PROBLEM TO BE SOLVED: To provide a flame-retardant fiber sheet, which hardly causes corrosion of an electronic component or metallic component when used as a cushioning material.SOLUTION: A flame-retardant fiber sheet to be used as a cushioning material has flame retardancy since fibers are mutually adhered by a binder containing a phosphate flame retardant. Further, since a phosphate flame retardant having an elution ratio of phosphate ions to 100°C water of 15 ppm (parts per million) or less is used as the phosphate retardant, phosphate ions are unlikely to elute from the binder to corrode the electronic component or metallic component. Thus, the sheet hardly causes the corrosion of the electronic component or metallic component when used as the cushioning material. |
