摘要：
A holding and sealing material for a catalytic converter for disposition between a cylindrical catalyst carrier and a metal shell covering the outer periphery of the catalyst carrier. The holding and sealing material includes a fiber aggregate mainly formed of alumina-silica based ceramic fibers having a mullite crystal content of 10 wt % or less, and the fiber aggregate is subjected to a needle punch treatment. Owing to the improved holding and sealing material, a catalytic converter having excellent durability and assemblage and having extremely low pollution characteristics is provided.
