Abstract:
A water repellent film (200) according to the present invention includes a first layer (10) having a plurality of fine protrusions (100) on the surface thereof, a second layer (20) covering the fine protrusions (100) and having a water repellent property, and a third layer (30) provided on the surface of the first layer (10) on the opposite side of the fine protrusions (100). When a modulus of elasticity of the first layer (10) is defined as E1, a modulus of elasticity of the second layer (20) is defined as E2, and a modulus of elasticity of the third layer (30) is defined as E3, a definition of E2>E1>E3 is fulfilled. Accordingly, the water repellent film having excellent resistance to abrasion in which a fine structure is not easily abraded and damaged by an external friction force or the like can be obtained.
