In an exhaust purification device for a diesel engine, an electric heating element is disposed in an exhaust passage, and the filter member collects particulate components in the exhaust gas, and an electric heating element is disposed in a cell to burn and remove the particulate components. The electric heating element disposed at the periphery of the filter member and the electric heating element disposed at the center are connected in parallel to the power supply, and the electric resistance of the electric heating element at the periphery is used to generate the electric heating at the center. A diesel engine exhaust purification device characterized by having a large electrical resistance compared to the body's electrical resistance.
