Abstract: A conductive fiber and a method for fabricating the conductive fiber are provided. The method for fabricating the conductive fiber includes the following steps. A first solution is provided, where the first solution includes a spinnable polymer dissolved in a first solvent, wherein the weight ratio of the spinnable polymer to the first solvent is from 5:95 to 20:80. A second solution is provided, wherein the second solution includes a conductive material dispersed in a second solvent, and the weight ratio of the conductive material to the second solvent is from 5:95 to 20:80. The shape of the conductive material is dendritic or snowflake-like. Next, a wet spinning process employing the first solution and the second solution is performed to obtain the conductive fiber.
