Abstract
A plate-shaped catalyst for denitration of exhaust gases has a surface roughened expanded metal base strip that is coated on both surfaces with a catalytic layer. Conical convex and concave portions adjoining one another are pressed into the coated strip, and the surfaces of the coated layer are formed with wave-shapes having a predetermined pitch without substantially deforming the expanded metal strip. The plate-shaped catalysts are stacked on one another to form a catalytic unit using the convex and concave portions as spacers.
