Provided is a novel method for producing a chip having a water-repellent front surface and a hydrophilic back surface. For this purpose, the production method according to the first embodiment of the disclosure of the present invention includes a step of bringing a front surface (811a) of a chip (811) having a hydroxyl group into contact with an organic solution (905), which is obtained by dissolving R1-Si(OR2)3 or R1-SiY3 in a second hydrophobic solvent (905a), while protecting the back surface (811b) of the chip (811) by means of a water film (902), thereby forming a thin water-repellent film on the front surface (811a) of the chip (811). |
