PURPOSE:To remove combustible fine particles efficiently, by arranging a self- current passing abd heat generating type heater to the upstream side of a filter. CONSTITUTION:A self-current passing and heat generating type heater 1 comprising a ceramic sponge like structure and a filter 2 are bonded under baking at each one end surfaces by a ceramic paste to form the interface 7 therebetween and form integral consitutiton. In addition, to the other end surface of the heater 1, a metallic electrode is formed as a metallized layer 3 and, to the other end surface of the filter 2, a metallic electrode is further formed as a metallized layer 4. With the metallized layers 3, 4, circular corrugated metal nets 5, 6 made of stainless steel are contacted in an electrically connected state. In addition, a lead wire 13 is electrically connected to the metal net 6 at a soldering part 13a and guided to the external part of an outer cylinder 9 through an insulator 11 to be connected to a power source E. |
