The evaporation of the stripping liquid 6 changes the concentration of the standard electrolyte. This causes the quantification accuracy of the chemical substance to be lowered. In order to solve the above problem, this invention provides a method for quantifying a chemical substance contained in a sample solution, characterized by the following stripping gel. The stripping gel covers the stripping electrode, and contains a standard electrolyte and an ionic liquid; however, the stripping gel contains no water. Furthermore, the ionic liquid is hydrophobic and nonvolatile, and the standard electrolyte is consisted of the anion and a metallic ion.
