摘要:
To provide a gas sensor element having a base body whose durability is unlikely to deteriorate during the use and exhibiting excellent endurance and responsiveness.[Means for Solution] A gas sensor element 2 comprising: a closed-bottomed cylindrical base body 28 made of solid electrolyte which contains zirconia as a principal component; an outer electrode 26 formed on an outer surface of the base body 28; an inner electrode 27 formed on an inner surface of the base body 28; and an adhesive layer 29 formed between the base body 28 and the outer electrode 26 and containing zirconia as a principal component, wherein a proportion of tetragonal in zirconia particles of the base body 28 falls within the range from 45% or more to 60% or less and, wherein a proportion of tetragonal in zirconia particles of the adhesive layer 29 is greater than that of tetragonal in zirconia particles of the base body 28.
