Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sacrificial electrode material that can maintain the activity of a sacrificial electrode even when there is a decrease in pH around the sacrificial electrode.SOLUTION: A sacrificial electrode material has a sacrificial electrode electrically connected to a metal material buried in a structure, and an exterior part having the sacrificial electrode buried therein and having a predetermined shape. The exterior part is formed so that a pH around the sacrificial electrode becomes 3 or more and 11 or less.SELECTED DRAWING: None 【課題】犠牲電極の周囲のｐＨが低下しても犠牲電極の活性を維持することができる犠牲電極材を提供することを課題とする。【解決手段】構造物に埋設された金属材料に対して電気的に接続される犠牲電極と、該犠牲電極が埋設されて所定形状を有する外装部とを備える犠牲電極材であって、前記外装部は、犠牲電極の周囲のｐＨが３以上１１以下となるように形成されることを特徴とする。【選択図】なし
