GAS SENSOR ELEMENT AND GAS SENSOR |
| 摘要 |
A sensor element includes a sensor element main body a including an oxygen ion-conductive solid electrolyte layer and a porous protective layer covering at least part of the sensor element main body. Then, the porous protective layer has the value of the number of interfaces in a unit thickness direction, which is the number of particle interfaces of constituent particles every 100 μm in the thickness direction, of 15 or more and 250 or less. |
