Abstract
An exhaust gas cleaning device is constructed of a honeycomb core body formed by superposing in a contiguous relation a planar band made of a metal sheet and a corrugated band made from another metal sheet one over the other. The honeycomb core body defines a number of network-patterned axial gas flow passages and is adapted to carry an exhaust gas cleaning catalyst thereon. The planar band has alternating rugged sections and flat sections of desired lengths.
