An object of the present invention is to provide a mass spectrometry chip for LDI-TOFMS for efficiently concentrating and drying a sample, particularly a very small amount of a sample. In addition, after the sample is dried, a chip for mass spectrometry to be used as a substrate for LDI-TOFMS measurement is provided. A hole is formed in a substrate by etching or the like. A sample solution is dropped into the hole 103 to obtain a dry sample. The obtained dried sample is subjected to LDI-TOFMS measurement together with the substrate 101. [Selection] Fig. 2 |
