摘要：
An object of the present invention is to provide a spark plug which has more excellent impact resistance with electrical conductivity and airtightness kept excellent. In the invention, each of first and second electrically conductive sealing layers (17) and (19) is made of electrically conductive glass containing a glass component and a metal component. The metal component at least contains a Cu—Zn alloy which contains Cu as a first component, and Zn as a second component.
