A metal-made carrier body, for carrying thereon an exhaust gas cleaning catalyst, comprises a metal casing, and a multi-layered composite structure or honeycomb core structure composed of a sheet-like metal band and a corrugated metal band and enclosed in the tubular metal casing and joined therewith. The inner wall of the casing is provided with brazing-material-holding grooves. Because of the brazing-material-holding grooves, it is possible to join the honeycomb core structure and the casing together with adequate firmness, thus making the carrier body excellently durable.
