A waterdrop slidable surface structure, which makes waterdrops dropped onto a substrate slide on a surface of the substrate, includes a waterdrop slidable layer arranged on the surface of the substrate and including a rigid layer (40) and a water repellent layer (31). The rigid layer (40) contains a rigid material having higher hardness than the substrate and provides a continuous depression and protrusion surface. The water repellent layer (31) mainly consists of a water repellent material of which contact angle for waterdrops dropped thereon is equal to or more than 90 degrees, and is filled in depression portions of the rigid layer. <IMAGE> <IMAGE> |
