The invention relates to an RFID tag (10, 40, 60, 80), which is suitable for mounting on surgical instruments and by means of which encapsulation of the RFID elements from the surroundings, good cleanability, and improved detectability can be achieved, in addition to stable anchoring on the instrument. The RFID tag comprises a metal holder (12, 42, 62, 82), a housing (14, 44, 64, 84), which is made of electrically non-conductive or slightly conductive material and has an accommodating chamber (18, 48, 88), and an RFID element (16, 46, 66, 86) having an antenna (22, 56, 92), which RFID element is arranged in the accommodating chamber of the housing, wherein the housing has a first end, which is retained on the metal holder, wherein the accommodating chamber is formed in the housing at a spatial distance from the first end of the housing and wherein the RFID element is positioned in the accommodating chamber in such a way that the antenna of the RFID element is spatially arranged substantially outside of the metal holder.
