Abstract
The reliability of the airtight sealed section is improved by providing a metallic or ceramic insertion member at a portion positioned between an electricity introducing member and a narrow tube in the airtight sealed section. The difference between the inner diameter of the narrow tube and the outer diameter of the insertion member is made 0.02 to 0.6 mm. The electricity introducing member is constructed by a halogen-resistant first member and a second member whose coefficient of linear expansion is similar to that of the narrow tube, and the junction of the first member and second member is covered with a halogen-resistant glass sealant. The difference between the insertion length of the second member into the narrow tube and the flow-in length of the glass sealant into the narrow tube is made 1 mm or more.
