Abstract
An inside lead portion of a gas sensor element has a lanthanum zirconate layer arranged between an electrically conductive oxide layer and a solid electrolyte member. Meanwhile, an inside detection electrode portion of the gas sensor element is formed such that (i) no lanthanum zirconate layer is formed between an electrically conductive oxide layer and the solid electrolyte member, or (ii) a lanthanum zirconate layer thinner than the lanthanum zirconate layer of the inside lead portion is formed between the electrically conductive oxide layer and the solid electrolyte member.
