Abstract
A metal-made honeycomb carrier body is provided for carrying thereon an exhaust gas cleaning catalyst. The carrier body has been formed by superposing a planar metal band made of a metal sheet and a corrugated band made from another metal sheet one over the other in a contiguous relation and defines a number of network-patterned gas flow passages along a central axis thereof. At one of opposite axial ends of the honeycomb carrier body, one of the planar band and the corrugated band extends outwardly relative to the other band.
