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 outer casing for a gas sensor includes a cap, a mount base, and a heat shielding board. The cap, the mount base, and the heat shielding board are made of gas permeable ceramics. A target gas flows inside the gas sensor with the above outer casing from all directions, and makes the gas sensor highly responsive to the target gas. The outer casing also contributes to make temperature and humidity inside the gas sensor uniform in a short time, thereby stabilizing an output voltage of the gas sensor.

摘要： The catalytic combustion type gas sensor includes a sensing element, a heat conducting layer of which includes boron nitride. The boron nitride content is from 30 wt % to 100 wt % of a material (such as alumina) that would be a base material having the highest proportion in a conventional heat conducting layer without boron nitride. A catalyst layer of the sensing element also includes boron nitride. The boron nitride content is from 10 wt % to 80 wt % of a material (such as tin oxide) that would be a base material having the highest proportion in a conventional catalyst layer without boron nitride.
