。[Claims for Utility Model Registration] A first cell defined by an air-permeable partition wall, which is open on the upstream side of the exhaust gas and sealed with a plug member on the downstream side of the exhaust gas, and a first cell defined by the partition wall. and a second cell disposed adjacent to the first cell, the downstream side of which is open and the upstream side of which is sealed by a plug member, and the first cell captures particulate matter being exhausted. In the exhaust gas purification device of the reverse flow regeneration type, in which the regeneration gas is caused to flow from the downstream side of the filter toward the upstream side during filter regeneration, a plug member for sealing the first cell is provided. 1. A backflow regeneration type exhaust gas purification device, characterized in that an electric heater wire is buried, and a portion of the heater wire exposed from the plug member does not cover the second cell.
