A conductive fiber including a metal-nanobelt-carbon-nanomaterial composite. A manufacturing method thereof includes preparing a composite including a carbon nanomaterial and metal nanobelts and manufacturing a conductive fiber by mixing the composite with a polymer. A fibrous strain sensor and a manufacturing method thereof are also provided. Thereby, a conductive fiber including a metal-nanobelt-carbon-nanomaterial composite, which is able to increase conductivity of the conductive fiber through synthesis of metal nanobelts enabling area contact and to exhibit good contact between the carbon nanomaterial and the metal nanobelts due to formation of the metal nanobelts on the surface of the carbon nanomaterial and superior dispersion uniformity, and a fibrous strain sensor including the conductive fiber can be obtained. The conductive fiber can be effectively applied to a strain sensor based on a principle by which resistance drastically increases with an increase in a distance between metal nanobelts aligned in a fiber direction upon tensile strain of metal nanobelts enabling area contact.
