Abstract:
1. An electrically heated catalyst comprising: a heat generation element that is adapted to be electrically energized to generate heat; a case that contains said heat generation element therein; a mat that is arranged between said heat generation element and said case, and serves to insulate electricity and at the same time to support said heat generation element; an electrode that is connected to said heat generation element from outside of said case; an insulation part that plugs a gap between said case and said electrode; an electrode chamber that is a space formed around said electrode at an inner side of said case and at an outer side of said heat generation element, and is formed by providing a gap between said electrode and said mat; and a partition part that is arranged in said electrode chamber at an upstream side of said electrode in a direction of flow of an exhaust gas, in such a manner that the exhaust gas flowing through the interior of said electrode chamber impinges against said partition part.
