PROBLEM TO BE SOLVED: To evaluate corrosion resistances of many materials electrochemically by one electrode and install an apparatus compactly in a small space inside an actual plant or the like. SOLUTION: A corrosion test stand 1 is constituted which includes a counter electrode 7, a reference electrode 8 having a plurality of salt bridge Luggin tubes 9 in the periphery and a specimen holder 6 for holding the reference electrode 8 and specimens 10 arranged in the vicinity of leading end parts of the plurality of salt bridge Luggin tubes 9. The corrosion test apparatus comprises the corrosion test stand 1, a potentiostat and a switch box with a timer for sequentially switching and electrically connecting lead wires 4a of the specimens 10 to the potentiostat.
