A gas sensor and a related manufacturing method are disclosed. The gas sensor includes a detecting unit comprised of a concentration detecting element, composed of a solid electrolyte body having inner and outer walls formed with electrodes, a housing, output terminals and a heater, and an output extracting unit comprised of at least signal wires, power conducting wires, output extracting terminals, power conducting terminals, an insulator and a casing. The detecting unit and the output extracting unit are united to each other in the insulator such that the output terminals, holding a base body of the heater in electrical insulation, and the output extracting terminals are conducted to each other and the heater electrodes and the power conducting terminals are conducted to each other upon which a boss portion of the housing is fixedly fitted to a leading end portion of the casing.
