Abstract: A sample plate for a solid sample includes a plate-shaped main body and lid. The main body has a concave portion, in which a sample placement platform shaped like a cylinder protrudes from the central area of the bottom surface of the concave portion. The lid has a funnel-shaped opening bored at a position immediately above the concave portion. The diameter of the opening on the lower side is approximately the same as that of the sample placement platform. After a sample, e.g. a biological tissue section, is placed in the concave portion, the lid is closed. Then, the lower wall surface of the lid surrounding the opening presses the sample downward. The sample is thereby sandwiched between the lower wall surface and the sample placement platform. A solvent for ionization is injected into the opening whose lower side is thus closed by the sample.
