摘要：In a gas sensor, when an arithmetical mean roughness Ra of an inner peripheryof a metal tube is 1 μm or less and end portions and of U-springs are formed as curvedcontact portions, the end portions and of the U-springs can slide smoothly along the
inner periphery of the metal tube . Therefore, when vibration is applied to the gas sensor,the U-springs can be prevented from being caught in the inner periphery of the metaltube , and the vibration can be absorbed by an elastic function of the U-springs . Even ifthe gas sensor vibrates, defective contact between a sensor element and contact fittingsand wear and cracks in the sensor element are less likely to occur. That is, the gas sensorresistant to vibration can be obtained.
