The results of exposure test by using the test piece which simulates cathodically protected marine steel structure are reported. The exposure examination used the test piece which applied seawater resistant stainless steel from splash zone to the upper part of submerged zone. The value of cathodic current to submerged zone after five months was almost equal to carbon steel. But, cathodic current to seawater resistant stainless steel near high water level was smaller than the value of carbon steel. And, the cathodic current to the high water level of spring tide was larger than other parts.
