The invention provides a unit type metallic carrier of good durability and economical efficiency comprising a unit member which includes wire engagements and a metallic wire arranged on the wire engagements, in place of conventional metallic honeycomb bodies of honeycomb construction which serve to carry an exhaust gas purifying catalyst and comprise an expensive band material in the form of a flat plate and a band material (foil material) in the form of a corrugated plate. More specifically, in the invention, the unit member for the metallic carrier, which comprises two or more cylindrical-shaped wire engagements (C1 to Cn, n >/= 2) and a metallic wire (W) arranged on the wire engagements, is constituted such that (i) the respective wire engagements (C1 to Cn, n >/= 2) constituting said unit member comprise engaging portions (O1, O2, ... On) provided on an outer peripheral wall portion thereof for engaging with said metallic wire (W) in a parallel position between the respective wire engagements, (ii) said engaging portions comprise a specified number (m) or engaging means (O11-O1m, O21-O2m, ... Onl-Onm) arranged at a desired pitch (p), and (iii) said metallic wire (W) is arranged on said engaging means.
