    摘要： A powder filler is stuffed in a filler space defined between a housing and a gas sensing element so as to airtightly seal a clearance between the housing and the gas sensing element. The powder filler contains grains whose diameter is in a range from 80 μm to 5,000 μm when measured before being stuffed into the filler space. A weight percentage of the grains having the diameter of 80 μm to 5,000 μm is equal to or larger than 80% with respect to an overall weight of the powder filler.

    摘要： A gas sensor has a sensor element inserted in a cylindrical housing. A measured gas cover, provided at a distal end side of the housing, forms a measured gas environment at a distal end side of the sensor element. An atmospheric air cover, provided at a proximal end side of the housing, forms an atmospheric air environment at a proximal end side of the sensor element. A clearance between an inside surface of the housing and an outside surface of the sensor element is gastightly sealed with a sealing member including a plurality of powder filler layers to separate or isolate the measured gas environment from the atmospheric air environment.

    摘要： A gas sensor has a cylindrical housing case, a gas sensor element as a sensor component, and a filler portion. The filler portion is formed between the inner surface of the cylindrical housing case and the outer surface of the gas sensor element. The filler portion is filled with filler powder composed of talc as a layered compound. Talc is a principal ingredient of the filler powder. The space formed between the cylindrical housing case and the gas sensor element is sealed with the filler powder in the filler portion. The filler powder in the filler portion has a degree of c-axis orientation within a range of 60% to 85%, The filler powder in the filler portion has a porosity of not more than 10%.

    摘要： A gas sensing member has a unit structure and a porous protective layer disposed on the unit structure. The unit structure has a solid electrolyte body, a gas measurement electrode disposed on a surface of the body and exposed to a measured gas entering at a gas inlet, a reference gas electrode disposed on another surface of the body and exposed to a reference gas, and a heater disposed close to the body. The heater has a heater substrate and heating elements disposed in the heater substrate. The heating elements heat the body. The heater substrate has side corner areas placed on side corners of the unit structure and being adjacent to the heating elements. The protective layer is disposed on the gas inlet such that the side corner areas are not covered with the protective layer and are directly exposed to the measured gas.
