Abstract
A catalytic converter has a ceramic catalytic support, a cylindrical casing for holding the catalytic support therein and a holding member disposed between the catalytic support and the casing. The holding member has a plurality of net-like layers, each of which is parallel to a circumferential surface of the catalytic support and has fibers randomly tangled with each other. Because of this structure, when the catalytic converter is assembled, damage to the fibers and separation of the fibers of the holding member can be prevented. As a result, the holding member can securely and steadily hold the catalytic support within the casing.
