Abstract
A catalyst device includes a heating element that generates heat when energized, a case that accommodates a catalyst support (heating element), an inflow pipe that draws exhaust gas into the case, and a connecting pipe that connects the inflow pipe and the case to each other. The case includes an end portion, which protrudes further in an upstream direction than an end face of the catalyst support. The inflow pipe is disposed inside the case. The catalyst device includes a triple-walled pipe structure, in which the connecting pipe overlaps with the end portion of the case and the inflow pipe in a covering manner.
