Beschreibung
Zusammenfassung:	Provided is a catalyst device that makes it possible to efficiently purify exhaust gas. A catalyst device (36) that comprises: a carrier (42)that is formed by stacking and rolling a metal-foil-shaped flat plate (52) and a metal-foil-shaped corrugated plate (54) and that carries a catalyst; and an outer cylinder (44) that houses the carrier (42) and supports the carrier (42) such that one end part (42a) of the carrier (42) is oriented toward an exhaust gas upstream side and another end part (42b) of the carrier (42) is oriented toward an exhaust gas downstream side. The flat plate (52) and the corrugated plate (54) have a plurality of holes (64) and are covered by a coating film that includes a catalyst substance. The coating film that covers the downstream side of the holes (64) is thicker than the coating film that covers the upstream side of the holes (64) .
