Abstract
A heating device comprises a heating element, permeable to the exhaust gas, and intended to be traversed by the exhaust gas flowing in a longitudinal direction. The heating element comprises two electrical poles, and two electrodes, each electrode being solidly attached to a respective electrical pole. Each electrode has a generally elongated shape along a respective elongation direction. At least one of the electrodes has a direction of elongation substantially parallel to the longitudinal direction.
