The utility model belongs to the technical field of automobile tail gas treatment, and particularly relates to a honeycomb ceramic carrier for an automobile. Aiming at the problem of low overall utilization rate of a catalyst caused by uniform distribution of carrier pore channels in the prior art, the utility model provides the honeycomb ceramic carrier for the vehicle, which comprises a carrier body, and a high-density pore area close to the central position and a low-density pore area close to the edge position are arranged in the carrier body. The number of pore channels in the unit area of the high-density pore area is larger than that of pore channels in the unit area of the low-density pore area, and the high-density pore area and the low-density pore area are isolated through a transition wall. According to the utility model, the interior of the carrier body is divided into the high-density pore area close to the central position and the low-density pore area close to the edge position by the transiti
