<P>PROBLEM TO BE SOLVED: To produce a honeycomb catalyst having a high reaction efficiency and so easily producible as to lower the cost and a production method therefor. <P>SOLUTION: The honeycomb catalyst is produced by forming a large number of recessed grooves 2 in a flat sheet 1 made of a foamed metal for forming an uneven shape, packing a catalyst 3 in the projections 2a, and spirally rolling the flat sheet 1 having the uneven surface in a manner that the direction of the grooves 2 is coincident with the axial direction of the rolling. The projections 2a of the foamed metal have a function as a catalyst support and the recessed grooves 2 have a function as gas flow channels. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
