PROBLEM TO BE SOLVED: To provide a mass analysis-use measurement sample and a preparing method for the same, which dramatically increase an ionization efficiency of a sample containing a measurement object molecule in a laser irradiation operation, and bring a sweet spot to appear easily, or a lot of sweet spots or a wide sweet spot to appear, and to provide a mass analysis for improving the ionization efficiency and the measurement in repeatability in order to obtain information about a reliable chemical structure, even in the case the sample containing the measurement object molecule is very minute, by using the above sample and method. SOLUTION: The mass analysis-use measurement sample is prepared from a matrix and a sample containing the measurement object molecule, and is characterized by having a wavelike structure whose average period is 1 to 300 nm on at least one portion of its surface.
