提案されている。Therefore, it has been conventionally considered that the catalyst carrier carrying the catalyst has an electric heater structure. By the way, in recent years, a catalyst carrier to which a metal catalyst carrier is applied, which is advantageous in terms of heat capacity and pressure loss, has been considered. Since this metal catalyst carrier is composed of a metal plate, an exhaust gas purification catalytic converter device has been proposed in which the metal plate itself is used as a heating resistor, that is, an electric heater.

の電極を接続した構造となっている。As a conventional catalytic converter device, there is, for example, one shown in US Pat. No. 4,928,485. In this structure, a metal plate supporting a plurality of catalysts that are bent in a wavy shape in a radial direction is spirally wound around a rod-shaped center electrode, and each outer peripheral end is connected to one annular metal plate. In the above structure, the other electrode is connected via the annular metal plate.

が偏るという問題もある。In the conventional electrode mounting structure of the catalytic converter device, the electrode member and the metal catalyst carrier are spot-welded at several points, but this cannot secure a wide contact surface, and thus the contact surface cannot be secured. There is a drawback that the resistance value of the portion becomes large and heat is generated locally to easily cause melting damage. Also,
There is a metal catalyst carrier formed by alternately laminating corrugated plates and flat plates, and there is also a structure in which an electrode member is brazed and attached to the outer surface of the flat plate. In this case, the contact area between the electrode member and the metal catalyst carrier can be increased, but since the contact area between the corrugated plate and the flat plate is small, the resistance value of the contact portion becomes large and local heat is likely to be generated.
Further, with respect to the plate brazed to the electrode member, the further the plate is from the plate, the more difficult it is for the current to flow due to the effect of contact resistance, and the heat generation distribution becomes uneven.

Since the end portions of the corrugated plate and the flat plate are crushed and brazed in surface contact with each other, electrical contact resistance from the electrode member to the metal catalyst carrier is reduced as much as possible.
