    Abstract: An electrically-heated catalytic converter includes: a substrate made of ceramic, the substrate including a catalyst coated layer; electrode films made of ceramic, the electrode films being disposed on a surface of the substrate; electrode terminals made of ceramic, each of the electrode terminals being secured to a corresponding one of the electrode films; and external electrodes each attached to a corresponding one of the electrode terminals via a brazing filler metal. A thermal expansion coefficient of the brazing filler metal is equal to or higher than a thermal expansion coefficient of the electrode terminals, and is equal to or lower than a thermal expansion coefficient of the external electrodes. The thermal expansion coefficient of each of the electrode terminals decreases from a portion at which the electrode terminal is joined to the brazing filler metal toward a portion at which the electrode terminal is joined to the corresponding electrode film.
