The invention comprises a security substrate for making security documents and the like comprising a fibrous base substrate and an elongate security element at least partially embedded therein. At one surface of the security substrate one portion of the security element is exposed to provide a continuous track along the length of the security element. A plurality of other portions along at least one edge of the security element are partially covered by overlapping regions of the fibrous substrate. The invention further comprises a method of manufacturing such a security substrate.
