A method for assembling a metal honeycomb catalyzer carrier includes the steps of winding corrugated belt plate materials into a substantially cylindrical shape, forming a wound structure into a predetermined cylindrical shape with a die 101 and pushing out a wound honeycomb body 12 obtained through the forming from the die and inserting the wound honeycomb body 12 into the interior of a tubular member 13. An assembling apparatus 31 includes a winding unit 42 which includes, in turn, a rotational holding shaft 167 and a press roller unit 38, a die unit 39 for forming a wound structure wound round the rotational holding shaft 167 into a wound honeycomb body 12 of a predetermined cylindrical shape (of an outside diameter Dp), a tube support unit 132 for setting a tubular member 13 at an edge of a die surface 126, and a honeycomb push-out and insertion unit 34 for pushing out a formed structure from a die 101 and inserting the formed structure so pushed out into the tubular member 13.
