An exhaust gas purification device for a ship 1 including: a main path 31 communicated with outside and a bypass path 32 branching off from a midway portion of the main path 31, each of the paths serving as an exhaust gas path 30 of an engine 25 to be mounted in the ship 1. A partition plate 40, by which the main and bypass paths 31, 32 are partitioned from the upstream side to the downstream side in an exhaust gas traveling direction, extends along the exhaust gas traveling direction. The partition plate 40 has a downstream end extended through between an exhaust gas outflow port 49 of the purification casing 33 and an exhaust gas outlet of the main path 31, and the downstream end is formed with an opening 401 to serve as a reverse-flow prevention plate 400.
