Abstract
A ceramic heater comprising a rod-like ceramic member in which a metallized layer is formed on at least a part of an outer surface of the ceramic member, and a tubular metal fitting in which at least a part of the ceramic member is inserted, the inner surface of the tubular metal fitting and the metallized layer being brazed through a brazing member. The ceramic member has a small diameter portion in a region which is located closer to a first end of the ceramic member than the metallized layer and which is inside the tubular metal fitting. A part of the space between the small diameter portion and the inner surface of the tubular metal fitting is filled with the brazing member, the inner surface facing to the part of the small diameter. Consequently, even under severe conditions, such as a high temperature and/or a high pressure, a highly durable brazing structure, such as the ceramic heater, including a brazed portion which has high welding reliability can be obtained.
