Beschreibung
Zusammenfassung:	A reductant injecting device includes: a honeycomb structure comprising: a pillar shaped honeycomb structure portion having a partition wall that defines a plurality of cells each extending from a fluid inflow end face to a fluid outflow end face; and at least one pair of electrode portions arranged on a side surface of the honeycomb structure portion; an inner cylinder being configured to house the honeycomb structure; a urea sprayer arranged at one end of the inner cylinder; and an outer cylinder arranged on an outer peripheral side of the inner cylinder, the outer cylinder being spaced apart from the inner cylinder. A flow path through which the carrier gas passes is formed between the inner cylinder and the outer cylinder.
