Abstract
A gas sensor element having a porous protective layer with excellent water repellency. Provided is a gas sensor element having a detection portion, which has a stack of a solid electrolyte body having a pair of electrodes on opposite sides thereof and a heat generating body including a heat generating source, and a porous protective layer formed around the detection portion. The porous protective layer has thermal conductivity λ in the range of 0.2 to 5 W/mK, and has λCpρ, which is the product of the thermal conductivity λ(W/mK), density ρ(g/m), and specific heat Cp(J/gK), in the range of 5.3×10to 2.1×10WJ/mK.
