摘要：
The present invention is intended to suppress a decrease in insulation resistance between electrodes and a case in an electric heating catalyst (EHC). An EHC (1) according to the present invention is provided with a heat generation element (3) that is energized to generate heat thereby to heat a catalyst, a case (4) that receives the heat generation element therein, an insulating member (5) that is arranged between the heat generation element (3) and the case (4) for insulating electricity, electrodes (7) that are connected to the heat generation element (3) through an electrode chamber (9) which is a space located between an inner wall surface of the case (4) and an outer peripheral surface of the heat generation element (3), and a ventilation passage (10) that ventilates the electrode chamber.
