PROBLEM TO BE SOLVED: To provide a detergent composition which is suitable for cleaning an object to be cleaned by using an automatic dishwasher having such a control mechanism that electrical conductivity of a detergent composition-containing cleaning liquid is monitored and whether the detergent composition is supplied or not is determined.SOLUTION: The detergent composition of a liquid state or a solid state is used for cleaning the object to be cleaned by using the automatic dishwasher having such the control mechanism that electrical conductivity of the detergent composition-containing cleaning liquid is monitored and whether the detergent composition is supplied or not is determined. The detergent composition contains a nonionic surfactant (A), a polymer electrolyte (B), an alkaline agent (C) and a chelating agent (D). When 0.5 g of the detergent composition of the solid state is dissolved in 1 L of water, the electrical conductivity of the detergent composition-dissolved water is 1.2 mS/cm or higher at 60°C. When 1 g of the detergent composition of the liquid state is dissolved in 1 L of water, the electrical conductivity of the detergent composition-dissolved water is 0.7 mS/cm or higher at 60°C.SELECTED DRAWING: Figure 1 【課題】洗浄剤組成物を含む洗浄液の電気伝導度をモニターして洗浄剤組成物の供給の要否を判断する制御機構を備えた自動食器洗浄機を用いて洗浄対象物の洗浄を行うために適した洗浄剤組成物を提供する。【解決手段】洗浄剤組成物を含む洗浄液の電気伝導度をモニターして洗浄剤組成物の供給の要否を判断する制御機構を備えた自動食器洗浄機を用いて洗浄対象物の洗浄を行うための液体又は固体の洗浄剤組成物であって、（Ａ）ノニオン界面活性剤、（Ｂ）高分子電解質、（Ｃ）アルカリ剤、（Ｄ）キレート剤を含み、洗浄剤組成物が固体の場合、水１Ｌに洗浄剤組成物を０．５ｇ溶解させた際の６０℃での電気伝導度が１．２ｍＳ／ｃｍ以上であり、洗浄剤組成物が液体の場合、水１Ｌに洗浄剤組成物を１ｇ溶解させた際の６０℃での電気伝導度が０．７ｍＳ／ｃｍ以上であることを特徴とする洗浄剤組成物。【選択図】図１
