• a filter member which is disposed in an exhaust gas passage of said internal combustion engine for collecting the particulates in the exhaust gases,
• said filter member being formed of ceramic and provided with a large number of interconnected passages for passing the exhaust gases therethrough;
• an electrical heating means composed of a ceramic base body having at least one heating element which is partially and integrally formed in said base body, said heating element being arranged about the axis of said ceramic base body uniformly;
• said ceramic base body being provided with opposed end surfaces and a large number of passages for passing the exhaust gases therethrough and one of said opposed end surfaces of said base body being closely adhered to an exhaust gas inlet end surface of said filter member;
• and
• an electric power supplying means for electrically connecting said heating element to an electric power source.
