PROBLEM TO BE SOLVED: To produce fiber, fabric or nonwoven fabric having the following four requirements for all of fiber, fabric or nonwoven fabric made of chemical fiber: firstly, not dependent on a material, a length or a shape; secondly, at a low production cost by using a low cost material; thirdly, with characteristics of metal and alloy; fourthly, the characteristics of metal and alloy are maintained even if a load is applied at processing time of the fiber, the fabric or the nonwoven fabric .SOLUTION: A metallic compound which precipitates metal by heating process or a plurality of kinds of metallic compound in which a plurality of kinds of metals are precipitated at the same time are adsorbed on a surface of fiber, fabric or nonwoven fabric made of chemical fiber, and heat decomposition of the metal compound is performed, or heat decomposition of the plurality of kinds of metal compounds are performed at the same tie. Thereby, the surface of the fiber, the fabric or the nonwoven fabric are covered by
