    摘要: A gas sensor having a gas sensing element, e.g. a solid electrolyte oxygen concentration cell, attached to a front end of a rod-shaped ceramic holder which is fitted in a tubular metal casing and a short rod-shaped ceramic plug fitted in a rear end portion of the tubular casing so as to leave a space between the rear end of the holder and the plug. Across the space, a plurality of lead wires attached to the sensing element extend through axial holes bored in both the holder and the plug. The space between the holder and the plug and the holes in the plug are filled with a hermetic sealant, which is preferably a lead glass solidified from molten state within the casing, to positively prevent gases subject to measurement from passing through the holes in the holder.
