摘要： An oxygen concentration sensor of this invention comprises an element and a diffusion hole. The element is exposed to a gas to be measured and has a chamber portion formed together with an oxygen ion conductive solid electrolyte. The diffusion hole is provided for restricting the flow of said gas to be measured into said chamber portion. Furthermore, the relationship 1.ltoreq.S/(L.multidot.V).ltoreq.5 is established with the diffusion hole having a cross sectional area S (mm.sup.2) and a length L (mm) and the chamber portion having a volume V (mm.sup.3). To do so, the oxygen concentration sensor can provide a stable output even if a pressure of the gas to be measured is abruptly changed.

摘要： A nonfragile ad quickly activatable structure of a gas sensor element which may be built in a gas sensor employed in an air-fuel ratio control system for automotive vehicles for measuring the concentration of gas such O2, NOx, or CO. The gas sensor element is made of a lamination of a measurement gas electrode, a reference gas electrode, and a heater. The heater works to elevate the temperature of the gas sensor element up to a given value required to bring the gas sensor element into an activated condition. The heater includes a heater substrate, a heating element, and power supply leads. A minimum distance X between an edge of the heater substrate and an edge of the heating element meets a relation of 0.1 mm≦X≦0.6 mm, thereby minimizing a thermal expansion difference between the heater element and the heater substrate to avoid cracks in a portion of the heater substrate near the heater element. It also becomes possible to elevate the temperature of the heating element up to a higher value, thereby allowing the gas sensor element to be activated quickly immediately after the power is supplied to the heating element.
