PROBLEM TO BE SOLVED: To provide a volatile component quantity measuring apparatus which is provided with a mechanism for correcting the effect of buoyance due to decompression in the apparatus for measuring volatile components in an object under the decompression. SOLUTION: In the volatile component quantity measuring apparatus, a mechanism for correcting the effect of buoyance due to changes in atmospheric pressure makes a correction based on the difference between a weight indicated value under the finally reached atmospheric pressure and the final indicated value at the restoration of pressure.
