The present invention is to provide a gas sensor element and a gas sensor including a porous protective layer having an inside region and an outside region which is resistant to peeling even when covering a tubular gas sensor element. The gas sensor element (3) includes: a solid electrolyte body (3s) having a bottomed tubular shape and a closed front end, and extending in the direction of an axial line O; an inside electrode (50) which is provided on an inner surface of the solid electrolyte body; an outside electrode (51) which is provided on an outer surface of the solid electrolyte body; and a porous protective layer (80) which covers the outside electrode, the porous protective layer has an inside region (81) which covers the outside electrode and an outside region (82) which covers the inside region and has a lower porosity than the inside region, and the outside region is formed of a sintered body of ceramic and glass.
