Disclosed is an exhaust purification device for engine, wherein a series of chemical reactions with urea SCR are efficiently performed within a filter. In an exhaust filter which can collect particulates in exhaust, a urea hydrolysis catalyst is supported by a first portion of an inner wall of a cell passage on the inlet side (inlet-side passage), and a first NOX reduction catalyst is supported by a second portion provided downstream of the first portion in the inner wall of the inlet-side passage. Further, in an inner wall of a cell passage on the outlet side (outlet-side passage), a second NOX reduction catalyst is supported by a third portion which overlaps with the first portion in a direction intersecting the flow of exhaust introduced to the exhaust filter, or provided downstream of the overlapping portion. An oxidation catalyst is supported by a fourth portion which is provided downstream of the third portion and overlaps with the second portion in the intersecting direction, or provided downstream of the overlapping portion.
