Abstract

A gas sensor element including a solid electrolyte body, a sensor electrode, and a reference electrode is provided. The solid electrolyte body has oxygen ion conductivity and includes a measurement gas surface to be exposed to a measurement gas introduced from the exterior and a reference gas surface to be exposed to a reference gas introduced from the exterior. The sensor electrode is provided on the measurement gas surface of the solid electrolyte body. The reference electrode is provided on the reference gas surface of the solid electrolyte body. The sensor electrode includes a porous body containing a solid electrolyte having oxygen ion conductivity and a precious metal, the peak pore size of the sensor electrode being 0.03 μm to 0.3 μm.
