摘要： A lead portion (25) of a heater coil (22) is constituted of a single coil wound into a coil and a bead portion (24) is constituted of a double coil formed by further winding the single coil into a coil. By constituting a detecting element (2) by burying the bead portion (24) in a heat conductive layer (21) and adhering a catalyst layer (23) on the surface of the heat conductive layer (21), improvement of the gas sensitivity and the response speed of a catalytic combustion gas sensor is facilitated. Zero point variation is reduced by improving impact resistance. When both ends of the heater coil are fixed to electrode pins, both ends of the heater coil are welded to the electrode pins using a resistance welding method, etc., with a platinum wire, etc., wound on a primary core wire, and thereafter, the primary core wire is melted and eliminated while leaving the platinum wire, etc., by a wet etching process.

摘要： An impregnated cathode and a method of manufacturing the same are provided for suppressing emission of unwanted electrons and particles generated from an excess electron emitting substance so as to achieve a steady electron emission characteristic. The impregnated cathode is placed directly beneath an electron emission hole of a first grid. The impregnated cathode is made up of a first sintered porous element whose surface functions as an electron emitting region and a second sintered porous element whose surface is a peripheral region other than the electron emitting region. The porosity of the first sintered porous element is greater than that of the second sintered porous element. Not only the first sintered porous element having the electron emitting region but also the second sintered porous element corresponding to the region around the electron emitting region is impregnated with the electron emitting substance. In addition, the amount of the electron emitting substance per unit volume contained in the first sintered porous element is greater than that contained in the second sintered porous element.
