Abstract
A method for producing a gas sensor element (), the gas sensor element including a diffusive porous layer () disposed in a measurement chamber () and exposed to the outside and a ceramic insulating layer () forming sidewalls of the measurement chamber. The method includes transferring green diffusive porous layer pieces () cut in advance so as to have prescribed dimensions onto a first ceramic green sheet (); applying an insulating paste which later becomes the ceramic insulating layer to the first ceramic green sheet; laminating the first ceramic green sheet onto a second ceramic green sheet () to form a ceramic laminate (); cutting the ceramic laminate along prescribed cutting lines C to obtain a plurality of gas sensor element pieces; and firing the gas sensor element pieces.
