摘要 |
Disclosed is a water-repellent film (200) comprising a first layer (10) which has multiple fine protrusions (100) formed on the surface thereof, a second layer (20) which covers the fine protrusions (100) and has water repellency, and a third layer (30) which is arranged on a surface of the first layer (10) which is opposed to the fine protrusions (100), wherein E1 which is the elastic modulus of the first layer (10), E2 which is the elastic modulus of the second layer (20) and E3 which is the elastic modulus of the third layer (30) meet the requirement represented by the formula: E2>E1>E3. In the water-repellent film, fine structures formed thereon are not abraded or damaged readily by a frictional force applied from the outside or the like. Therefore, the water-repellent film has excellent abrasion resistance. |
