PROBLEM TO BE SOLVED: To provide a tapping fixing element for an inorganic foundation structure, simply driven, having high load support capability immediately after screwing in, bearing higher load as compared with the conventional tapping fixing element, and removable. SOLUTION: In this fixing element for the inorganic foundation structure having a shaft 12 provided with a rotary holding means 17, the shaft 12 at least partially has a screw part 14 for tapping. Further in the fixing element at least partially coated with a film 21. The film 21 is polar thermoplastic resin. Preferably the thermoplastic resin is ethylene-vinyl acetate or thermoplastic polyurethane. Further preferably, the melting point of the thermoplastic resin is 50-150°C, and most preferably 50-100°C. Preferably the strength of the thermoplastic resin is 2-15 N/mm<SP>2</SP>at room temperature, and most preferably 2-10 N/mm<SP>2</SP>. COPYRIGHT: (C)2008,JPO&INPIT
