The invention relates to the field of honeycomb ceramic filters, and discloses a thermal-shock-resistant and asymmetric honeycomb ceramic wall-flow type filter. The filter comprises an inlet honeycombceramic surface and an outlet honeycomb ceramic surface; inlet passages and outlet passages are arrange on each of the inlet honeycomb ceramic surface and the outlet honeycomb ceramic surface; the inlet passages communicate with the outlet passages; the outlet ends of the inlet passages and the inlet ends of the outlet passages are blocked; the inner diameter of the inlet passages is larger thanthat of the outlet passages; each inlet passage has the square cross section and is provided with round corners, or two adjacent edges are connected by two connecting lines, or the two adjacent edgesare connected by two connecting lines and an arc, and the arc is located between the two connecting lines; and each outlet passage has the square cross section and can also be provided with round corners or chamfers. According to the filter, the cross sections of the inlet passages are subjected to round-corner, double-line or double-line and arc transformation, and the cross sections of the outlet passages are unchanged or are subjected to round-corner or chamfer transformation. The filter has the good mechanical property, the low back pressure and the excellent thermal shock resistance.
