Claims

[Scope of utility model registration request]

A container containing a filter capable of collecting exhaust particulates from a diesel engine is provided in the exhaust passage, a ceramic heater is arranged close to or in close contact with the filter on the upstream side of the filter, and by energizing the heater, the In an exhaust gas purification device for a diesel engine that ignites and burns exhaust particulates adhering to a filter, the ceramic heater has a substantially square shape that extends from the inner wall of the container to near the center and then back to the inner wall of the container. Consisting of a plurality of heater elements, one end of the heater element is fixed to the container wall via an insulating seal, the fixing means forms an anode electrode, and the other end of the heater element is conductively connected to the container wall. An exhaust gas purification device that is fixed and forms a ground pole.
