Abstract
A sensing element, disposed in a housing, has a gas contact portion exposed to a measured gas. A protective cover extends from a distal end of the housing so as to surround the gas contact portion of the sensing element. A first metallic cover surrounds signal output terminals and leads connected to the sensing element. In manufacturing the first metallic cover, a shot blasting is applied to a surface of a semi-finished product of the first metallic cover.
