とする排出ガス後処理装置。[Claim for Utility Model Registration] An exhaust gas after-treatment device for treating exhaust gas emitted from a diesel engine, which is disposed in the flow path of the exhaust gas and collects particulate matter in the exhaust gas. It comprises a ceramic honeycomb type particulate filter, a filter regeneration heater disposed upstream of the particulate filter in the flow direction of exhaust gas, and a current supply circuit that supplies current to the filter regeneration heater. An exhaust gas after-treatment device, characterized in that a thermal diffusion layer made of a material with good thermal conductivity is provided on the exhaust gas contact surface of the particulate filter to allow exhaust gas to pass therethrough.
