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.
