An exhaust gas cleaning metallic honeycomb body for supporting thereon an exhaust gas cleaning catalyst is described. The body is of a honeycomb structure formed by alternately superposing two types of corrugated bands made of metal sheets one over the other in a contiguous relation and defining a number of network-patterned gas flow passages along a central axis thereof. The two types of corrugated bands comprise:(i) a first corrugated band having a triangular waveform of the structure that substantially-equilateral triangles are continuously connected in a lengthwise direction; and(ii) a second corrugated band having a substantially a sinusoidal waveform.
