摘要
A holding material for a catalytic converter including a catalyst carrier having an elliptical cross section, a metal casing for receiving the catalyst carrier, and the holding material mounted on the catalyst carrier and interposed in a gap between the catalyst carrier and the metal casing, in which the holding material has a first portion and a second portion, and the first portion in contact with a region of the catalyst carrier, corresponding to 40 to 95% of a major axis centering on an intersection of an ellipse and a minor axis in the elliptical cross section of the catalyst carrier, is larger than the second portion in contact with any other region of the catalyst carrier in basis weight.
