Abstract:
This invention provides a gas sensing device and gas sensor including a porous portion in which a first porous portion absorbs phosphorus and silicone sufficiently so as to suppress generation of clogging in a second porous portion meeting demands for intensifying the performance and accuracy of a gas sensor, so that the accuracy of detection of air-fuel ratio is further improved.
