PURPOSE:To collect corpuscles contained in exhausts out of a Diesel engine, by setting a calorific resistor with the upstream side of a filter's gas flow divided into at least three-area sections and exercising continuous rating heat controls over these divided resistors in order. CONSTITUTION:Three-groove structure bodies 21a-21c are constituted so as to divide the upstream surface of a flow of gas in a ceramic filter 13 into at least three-area sections, calorific resistors 15a, 15b and 15c are laid in them respectively, and these resistors are subjected to heat control upon being energized with current in turn. With this, since the calorific resistors 15a, 15b and 15c are supplied with heating power in order, the electric energy required to regenerate filter functions also gets off with a small one only. In addition, the regenerating portion also comes into a state of continuously collecting corpuscles from exhaust gases during regeneration so that filter's regenerative functions too may be highly streamlined, permitting miniaturization of the filter unit.
