A primary base fabric for a tufted carpet includes a first non-woven web and a second non-woven web laminated on each other. The first non-woven web is constituted with a first constituent fiber formed with a first thermoplastic resin and containing carbon. The second non-woven web is constituted with a second constituent fiber formed with a second thermoplastic resin and having a carbon content lower than the carbon content of the first constituent fiber or containing no carbon. The primary base fabric is a product prepared by combining the first non-woven web and the second non-woven web through an emboss processing.
