PROBLEM TO BE SOLVED: To provide a method and device for preparing a biochip that does not entwine a molecule, and does not cover a region required for hybridization. SOLUTION: In the biochip preparation method where a DNA, an RNA, or a protein cell 3 is prepared in an array shape on the surface of a substrate, the DNA, the RNA, or the protein chip is prepared by either one or both of a process for allowing solution containing the DNA, RNA, or protein to adhere from the lower part of the substrate, and a process for applying plus and minus voltages from both the sides of the substrate and solution adhering to a substrate 2.
