Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a substrate for mass spectrometric analysis with which it is possible to further advance the performance of a matrix-free ionization method and to conduct analysis by laser desorption ionization-mass spectrometry without requiring the use of an ionizing agent which is causative of noise or a decrease in detection sensitivity, and a method for producing the substrate. SOLUTION: The substrate for mass spectrometric analysis includes a base equipped thereon with a metal oxide to which an organic substance capable of supplying protons and/or cations is adherent. The method for producing the substrate for mass spectrometric analysis includes: coating the base with metal oxide dispersion obtained by dispersing the metal oxide with the aid of the organic substance capable of supplying protons and/or cations; and drying the coating.
