OXYGEN SENSOR ELEMENT |
| 摘要 |
An oxygen sensor element includes a solid electrolyte body having oxygen ion conductivity, a measuring electrode having catalytic action disposed on one surface of the solid electrolyte body, a reference electrode having a catalytic action disposed on another surface of the solid electrolyte body, and a heater for heating the measuring electrode. When the measuring electrode is heated by the heater, when measuring an oxygen concentration in a measured gas, a ratio (%) of an area of a low-temperature region where a surface temperature is less than 450 degrees C. relative to an area of a contact portion exposed to the measured gas G is 15% or less. |

1. An oxygen sensor element comprising:
a solid electrolyte body having oxygen ion conductivity; a measuring electrode having catalytic action disposed on one surface of the solid electrolyte body; a reference electrode having a catalytic action disposed on another surface of the solid electrolyte body; and a heater for heating the measuring electrode; wherein, when the measuring electrode is heated by the heater, when measuring an oxygen concentration in a measured gas, a ratio of an area of a low-temperature region where a surface temperature is less than 450 degrees C. relative to an area of a contact portion exposed to the measured gas is 15% or less. |
