Abstract
Official abstract text for this publication.
The electricity is suppressed from flowing through a case ( 5 ) of an electric heating catalyst ( 1 ). The electric heating catalyst ( 1 ) comprises a heat generating element ( 3 ) which generates heat by applying electricity; a case ( 5 ) which accommodates the heat generating element ( 3 ); an inner tube ( 4 ) which is provided between the heat generating element ( 3 ) and the case ( 5 ); and a mat ( 6 ) which is provided between the heat generating element ( 3 ) and the inner tube ( 4 ) and between the inner tube ( 4 ) and the case ( 5 ) and which insulates the electricity; wherein the inner tube ( 4 ) protrudes from the mat ( 6 ) toward an upstream side and a downstream side in a flow direction of an exhaust gas, the inner tube ( 4 ) is composed of at least two substances having different thermal conductivities, the substance ( 42 ) having the lower thermal conductivity is arranged on an inner side as compared with a surface, and the substance ( 41 ) having the higher thermal conductivity is arranged to surround the substance having the lower thermal conductivity.
