摘要： A prismatic multilayer gas sensor element and method of making the same, the prismatic multilayer gas sensor element (1) having a substantially rectangular cross section, and including a gas-sensing cell portion (2) formed at a distal end portion of the prismatic gas sensor element (1); and a posterior lead portion (3) adjoining the gas-sensing cell portion (2). The longitudinal lateral surfaces of the posterior lead portion (3) are coated with a non-porous alumina layer (11), the non-porous alumina layer (11) having a multilayered structure including at least a joining layer (11a) and a surface layer (11b). The longitudinal lateral surface of the gas-sensing portion (2) is not coated with a non-porous alumina layer.

摘要： A gas sensor including: a gas sensing element including first and second ceramic layers. The first ceramic layer has a first through hole and a first through hole conductor covering an inner surface thereof. The first ceramic layer includes a first conductor which includes: a first peripheral conductive portion electrically connected to the first through hole conductor; a first lead portion that is narrower than the first peripheral conductive portion; and a first contact conductive portion that is wider than the first lead portion. The first peripheral conductive portion, the first lead portion and the first contact conductive portion are integrally formed and arranged in this order in a longitudinal direction. The second ceramic layer includes a second conductor electrically connected to at least the first contact conductive portion.

摘要： A solid electrolyte layer or body capable of being co-fired with an insulating ceramic substrate or body to be used as a gas sensor laminate. The gas sensor laminate is preferably composed of an alumina substrate (1) and an oxygen-ion conductive solid electrolyte layer (6) bonded to the alumina substrate (1) by firing. The oxygen-ion conductive solid electrolyte layer or body is formed from partially or wholly stabilized zirconia, which layer contains alumina in an amount of 10% to 80% by weight, particularly 30% to 75% by weight. In this manner, another ceramic layer; particularly, a ceramic layer (7) of alumina can further be bonded to the oxygen-ion conductive solid electrolyte layer. The relative density of the ceramic layer can be 60% to 99.5%, preferably 80% to 99.5%.
