CATALYST DEVICE

Abstract:

Provided is a catalyst device that can equalize the strength of a carrier in the direction of the flow of exhaust gas. According to the present invention, a flat plate (52) and a corrugated plate (54) have a plurality of holes (64). When the flat plate (52) and the corrugated plate (54) are in a flat state before being made into a carrier (42), the plurality of holes (64) form: a plurality of first rows (66) that run along a first direction (D1) that is parallel to the axial direction of the carrier (42); and a plurality of second rows (68) that run along a second direction (D2) that is orthogonal to the first direction (D1). As seen from the second direction (D2), the holes (64) in one second row (68) and the holes (64) in the other second row (68) of adjacent second rows (68) have portions (64p) that overlap each other.
