Changing the uneven surface allow the water repellency to increase and decrease. The leaf of the lotus is known to form the water-repellent surface by a surface uneven and characteristic. In reference to it, I made the surface which changed surface height, the width of the column, a diameter. I made the water-repellent surface by applying water-repellent medicine to the uneven surface which I made. I drop a water on the surface which I made and observe the water-repellent increase and decrease by measuring a contact angle and a Sliding angle. As a result of measuring In a depth change, a sliding angle and a contact angle become constant in 50μm in depth or more together. In the change of the uneven, I understood that I could raise a sliding angle and a contact angle by lowering a diameter and the width of the column
