OG exemplary drawing
1. A sample support body comprising:
a substrate;
an ionization substrate disposed on the substrate; and
a support configured to support the ionization substrate with respect to the substrate such that a first surface of the ionization substrate which faces the substrate and the substrate are separated from each other,
wherein the ionization substrate has a plurality of measurement regions for dropping a sample on a second surface located on a side opposite to the first surface,
a plurality of through-holes that open in the first surface and the second surface are formed at least in the measurement regions of the ionization substrate,
a conductive layer is provided on peripheral edges of the through-holes at least on the second surface, and
the support has a first support provided on peripheral edges of the measurement regions on the first surface to separate the plurality of measurement regions when viewed in a direction in which the substrate and the ionization substrate face each other.
