An exhaust gas cleaning device comprises at least one exhaust gas flowing passage, at least one particulates collecting member composed of two filter elements having different heat capacity, which is disposed within the exhaust gas flowing passage and heating means which is interposed between the filter elements so as to be closely contacted therewith. The filter element having smaller heat capacity is disposed on the upper stream side of the heating means and the filter element having larger heat capacity is disposed on the downstream side thereof. The filter element having smaller heat capacity is rapidly heated by the heating means and the heat of the filter element having smaller heat capacity is transmitted to the filter element having larger heat capacity. All of the particulates collected by the particulates collecting member can be burnt off with excellent heat efficiency.
