    • PROBLEM TO BE SOLVED: To provide a method for simply obtaining a mass spectrum of high precision in a short time by automatically correcting the shift of spectrum peaks produced by the difference of altitude at respective points within a sample measuring surface in measurement using time-of-flight mass spectrometry. SOLUTION: In a method for correcting the mass error produced from the difference of altitude of the surface of a measuring sample in time-of-flight mass spectrometric measurement for obtaining the mass spectra of the whole of the region of the measuring sample by dividing the arbitrary region of the measuring sample into a plurality of measuring points and adding the measured spectra calculated at the respective measuring points, the shift from the rising positions of the arbitrary peaks at the respective detection positions of the measured spectra at the respective measuring points is calculated to be used in correction.
