PURPOSE: A device for reducing smoke for a diesel vehicle is provided to maximize a regenerating effect of a filter even if the exhaust temperature of exhaust gas is low by arranging filters depending on a thermal conduction rate. CONSTITUTION: A device for reducing smoke for a diesel vehicle comprises a pre-processing filter(110) and a post-processing filter(120). The pre-processing filter has a relatively high thermal conduction rate, and the post-processing filter has a relatively low thermal conduction rate. The pre-processing filter is composed of a metal filter, and the post-processing filter is composed of a ceramic filter. The ceramic filter is a wall-flow monolith filter.
