PURPOSE: An apparatus for electric anticorrosion is provided to enable replacement of a consumed anode plate or a consumed anode holder together with the anode plate by adopting impressed current cathodic protection for a vessel or a marine construction. CONSTITUTION: An apparatus for impressed current cathodic protection having a depressed configuration is installed in anode dual plates(73) superposed within an outer plate(70) of a vessel. The depressed apparatus has an anode plate(20), an anode holder(30) and a rod unit(50). The anode plate(20) is made of Pt plated Ti, Pt, graphite or an oxide of alloy. The anode plate(20) has a number of fitting holes at the periphery to be fixed by countersunk screws. In a central portion of the anode plate(20) is provided with a recess to be inserted into recesses of the anode holder(30). A screw(24) is inserted into a connector hole in the recess to be screwed into a block of the rod unit(50).
