Abstract
A gas sensor element () which includes an element body portion (); a pump cell () which is configured to adjust a concentration of oxygen in a gas to be measured which is introduced into the element body portion (); a detection chamber () which is formed inside the element body portion () and into which the gas to be measured in which the concentration of oxygen has been adjusted is introduced; and a layer-shaped cathode electrode () which is housed in the detection chamber () and configured to decompose NO. A relationship between a volume Vof the detection chamber () and a volume Vof the cathode electrode () in the gas sensor element () satisfies either one of conditions (A) and (B) as defined herein.
