Abstract
A method of manufacturing a gas sensor includes a step of printing a measuring electrode pattern on a ceramic green sheet for forming a measuring electrode, and a step of printing an electrode protection layer pattern on the measuring electrode pattern. The step of forming the protection layer pattern is performed by repeatedly printing a unit layer pattern several times by using a protection layer forming paste with ceramic powder mixed with a pore-forming agent in a predetermined ratio. A ratio of the pore-forming agent in the protection layer forming paste used for forming at least either one of a bottom unit layer pattern and an uppermost unit layer pattern is made larger than that of the pore-forming agent in the protection layer forming paste used for forming a unit layer pattern of other layers.
