Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an exhaust gas control device and a manufacturing method of the exhaust gas control device capable of enhancing regeneration efficiency of a DPF (diesel particulate filter). SOLUTION: The exhaust gas control device for controlling exhaust gas discharged from an internal combustion engine is provided with a gas flow passage in which the exhaust gas flows and the particulate filter 17, provided in the gas passage, in which many fine holes are formed. A substantially whole introduction face 171 of the particulate filter 17 contacting the exhaust gas is coated by a microporous body 18 wherein micropores having hole diameters shorter than that of a fine hole are formed.
