Beschreibung
Zusammenfassung:	[Problem] To improve purification performance in a honeycomb-type metal substrate while suppressing excessive generation of turbulence.[Solution] A honeycomb-type metal substrate in which flat metal foils and wavy metal foils are alternately layered, wherein: a plurality of holes are formed in the flat metal foil and in the wavy metal foil, and small burrs are formed on the edges of the holes; and the relationships 1.1 mm ≤ D ≤ 4.0 mm, 5% ≤ R ≤ 70%, and 0.1 µm ≤ L ≤ 30 µm are satisfied, where D is the average hole diameter of the plurality of holes, R is the opening rate, and L is the average height of the burrs.
