The present invention relates to a sample plate to be used for a MALDI-TOF (Matrix Assisted Laser Desorption Ionization Time of Flight) mass spectrometer, and more particularly, to a sample plate for a MALDI-TOF mass spectrometer, which is particularly useful for molecular weight measurement of a high-volatile material, a method of manufacturing the sample plate and a mass spectrometry method using the sample plate. Object of the present invention to provide a method capable of performing a mass spectrometry for a high-volatile material by using a MALDI-TOF mass spectrometer so as to overcome the limits of the gas chromatography method of the related art. According to the present invention, there is provided a sample plate including a target plate, an organic matrix formed on one surface of the target plate, a parylene thin film formed on the target plate having the organic matrix formed thereon and formed to cover the entire organic matrix, and a sample fixing layer formed on the parylene thin film. The sample fixing layer is made of at least one material selected from a group consisting of graphene and carbon nano tube (CNT).
