PROBLEM TO BE SOLVED: To provide a quantitative method for chlorine in a silver resin paste accurately and precisely. SOLUTION: In this chlorine quantitative method, a silver resin paste weighed on a sample dish is baked in a sealed container of the high-pressure oxygen atmosphere added with an alkaline solution, generated hydrogen chloride is absorbed by the alkaline solution, the combustion remainder left on the sample dish after combustion is put in the alkaline solution, the chlorine concentration of the processed solution is measured, and the chlorine in the silver resin paste is quantified based on this value.
