To provide a marine structure made of copper or copper alloy that suitably dissolves copper ion in the sea water throughout the season in any place to inhibit algae, shells and other organisms from fouling, and has a long life with excellent durability, and provide a corrosion-preventing method for the marine structure made of copper or copper alloy.
This marine structure made of copper or copper alloy 1 is electrically connected with a connecting means 7 via an adjustment 6 to a different metal 5 baser than the copper or the copper alloy provided in the vicinity of a draft part of the marine structure 1. The potential difference between the copper or the copper alloy wire net 10 constituting the copper or the copper alloy marine structure 1 and the different baser metal 5 are adjusted with the adjustment 6 to control the level of the corrosion of the copper or the copper alloy.
