Specimen testing plate structure, specimen testing apparatus, and specimen testing method

A specimen testing plate structure comprising:

• a first plate;
• and
• a second plate provided to face the first plate with a gap therebetween,
• wherein a first main surface, which exists on a first plate side, out of main surfaces of the second plate includes:
• a hydrophilic region;
• and
• a hydrophobic region adjacent to the hydrophilic region,
• wherein the hydrophilic region includes:
• a first hydrophilic region included in a region, free of facing the first plate, of the first main surface;
• and
• a second hydrophilic region included in a region, facing the first plate, of the first main surface,
• wherein the hydrophobic region includes:
• a first hydrophobic region included in the region free of facing the first plate;
• and
• a second hydrophobic region included in the region facing the first plate, and
• wherein a ratio of the second hydrophilic region to the second hydrophobic region and the second hydrophilic region is higher than a ratio of the first hydrophilic region to the first hydrophobic region and the first hydrophilic region.
