STRUCTURE FOR SUPPORTING CATALYST, AND CATALYTIC CONVERTER

摘要

To provide a catalytic converter that reduces non-uniformity of temperature of a catalyst support and that can approach a uniform temperature distribution, and a structural body for supporting a catalyst that structures this catalytic converter.
At a catalyst support (14), gradually decreasing width portions (14D), at which a width W thereof gradually decreases toward electrode centers (16C), are formed at regions where electrodes (16A), (16B) are contactingly disposed, as seen in a cross-section orthogonal to a direction in which exhaust flows. The width W is shorter than a length L1 of a center line CL at a given position. Heat generation and heat dissipation of the catalyst support (14) are balanced overall.
