Abstract
A self-heat generating type honeycomb filter is mounted in an exhaust pipe line of an engine, and a plane plate and a corrugated plate are layered, then wound, and the first slit portion and second slit portion having openings, respectively, are formed between an up-stream and down stream side end portions of the plane and corrugated plates. An electric current is applied between the up-stream and down stream side end portions, to heat the first and second slit portions. Accordingly, a self-heat generation type catalytic converter capable of realizing both high resistance and low thermal capacity, and further ensuring a reduction in thermal conduction, and durability, and raising the temperature up to the sufficient level with less power consumption, can be provided.
