Abstract
A method for manufacturing a gas sensor element (), which includes a plate-like second solid electrolyte member (), a fourth electrode () formed on the second solid electrolyte member (), and a protection layer () including a reinforcement member () having an insertion hole (), and a porous electrode protection member () provided in the insertion hole () and adapted to protect the fourth electrode () from becoming poisoned. The method includes a pressing step of, after disposing a green electrode protection member () in the insertion hole () of a green reinforcement member (), pressing at least one of the green reinforcement member () and the green electrode protection member () so as to form a green protection layer (); a laminate-forming step of arranging the green protection layer () and a green solid electrolyte member () in layers so as to form a laminate which will become the gas sensor element () after being fired; and a firing step of firing the laminate.
