Abstract
A laser desorption/ionization method, includes: a first step of preparing a sample support body including a substrate on which a plurality of through holes opening to a first surface and a second surface facing each other are formed, and a conductive layer provided on at least the first surface; a second step of introducing a sample and a solvent having refractoriness in a vacuum into the plurality of through holes; and a third step of ionizing a component of the sample by irradiating the first surface with laser beam while applying a voltage to the conductive layer.
