PROBLEM TO BE SOLVED: To develop a well plate that can easily put a test object such as a cell or a chemical solution into each well even if the diameter of the well is extremely small and the number of wells is extremely large. A well is formed in a resin layer formed on a glass surface, and the glass surface is exposed at the bottom of the well. Since the surface of the resin layer and the inner surface of the well become hydrophobic and the bottom surface of the well becomes hydrophilic, when a test object such as a cell is sprinkled on the well plate, the test object is selectively attached to the bottom of each well. To do. Thereafter, when the surface is lightly washed with water or alcohol, the test object adhered to other than the bottom of the well is easily removed, and the test object remains only at the bottom of the well.
