PROBLEM TO BE SOLVED: To rapidly quantify the content of the constituent elements of a solder alloy. SOLUTION: This method for quantitatively analyzing the constituent elements of the solder alloy containing tin and silver includes a process for decomposing a solder sample by nitric acid and a process for quantitatively analyzing the constituent elements in the decomposed solution. By this method, the solder sample can be decomposed without forming an insoluble component and the constituent elements of the solder alloy can be quantified rapidly and accurately.
