Abstract
Disclosed is a manufacturing method of a gas sensor element. The gas sensor element has a plate shape extending in a direction of an axis thereof and includes: a detection portion arranged on a front end side of the gas sensor element to detect a specific gas component in a gas under measurement; and a porous protective layer formed around the detection portion. The manufacturing method of the gas sensor element is characterized in that the porous protective layer is formed by press forming of a raw material powder.
