Abstract
In a gas sensor 10, a powder compact 45a seals a void space between an inner peripheral surface 42c of metal-made main hardware 42 and a sensor element 20, and the inner peripheral surface 42c has arithmetic average roughness Ra of 0.5 to 5 µm. The gas sensor 10 includes supporters 44a and 44b, which are arranged in a penetration hole of the main hardware 42, which allow the sensor element 20 to penetrate therethrough, and which press the powder compact 45a in sandwiching relation from both sides in an axial direction. A surface of at least one of the supporters 44a and 44b has the arithmetic average roughness Ra of not more than 0.5 µm.
