摘要： Provided is a sample support body that includes a substrate and an ionization substrate. The ionization substrate has a measurement region for dropping a sample on a second surface. A plurality of through-holes that open in a first surface and the second surface are formed in at least the measurement region of the ionization substrate. A conductive layer is provided on peripheral edges of the through-holes on at least the second surface. At least a part of the substrate which is adjacent to the ionization substrate is formed to enable the sample to move to the inside of the substrate.

摘要： A sample support body is for ionization of a sample. The sample support body includes a substrate including a first surface and a second surface on sides opposite to each other, and a conduction layer provided at least on the first surface. A plurality of through-holes opening on the first surface and the second surface are formed in an effective region of the substrate, the effective region being for ionizing components of the sample. A width of a first opening on the first surface side is larger than a width of a second opening on the second surface side in each of the plurality of through-holes.

摘要： Provided is a sample support body that includes: a substrate having a first surface and a second surface opposite to each other; and a conductive layer provided on at least the first surface. A plurality of through-holes, which open to the second surface and a third surface of the conductive layer which is located on a side opposite to the substrate, are formed in the substrate and the conductive layer. At least one of the second surface and the third surface is subjected to surface treatment for providing a difference in an affinity with water between a surface close to the second surface and a surface close to the third surface.
