ABSTRACT:
In an exhaust gas cleaning apparatus a ceramic heating resistor has a lattice-shaped exhaust gas passage and is formed by extrusion. The ceramic heating resistor is fixed closely to the upper stream side of a filter which catches particulates contained in exhaust gas. This heating resistor is divided into a plurality of sections so that heating current is successively supplied to the divided sections.
