PURPOSE: To raise a temp. till a catalytic activation temp. in a short time with low power consumption by making a thickness of a corrugated foil less than that of a flat foil so that a heat generation per volume of a heat releasing part may becomes large. CONSTITUTION: In an electrically heated carrier 2 obtained by arranging many brazing foils 8a and 8b between the corrugated foil 3 and the flat foil 4 and winding them cylindrically at a central electrode 5, the thickness of the corrugated foil 3 is made less than that of the flat foil 4 so that the heat generation per volume of the heat releasing part (hp) may becomes large among each element constituting an electricity conductive passage and a joining of the corrugated foil 3 and the flat foil 4 is executed partially. In this way, the heat generation per volume of the heat releasing part (hp) is enlarged without increasing the power consumption as a whole. Therefore, temp. rising rate of the heat releasing part (hp) is increased and the carrier is raised to the catalytic activation temp. in a short time. |
