PROBLEM TO BE SOLVED: To provide a device and a method for easily measuring a plurality of volatile component quantities in an object. SOLUTION: This volatile component quantity measuring device for evaporating the volatile components in the object by decompression, and measuring the volatile component quantities in the object from the weight difference before and after evaporation is characterized by being equipped with a data processing device for operating evaporation speed from a weight change curve during decompression, and operating simultaneously the constitutional ratio between a plurality of components having different evaporation speeds based on its inflection point.
