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 E 1 , a modulus of elasticity of the second layer ( 20 ) is defined as E 2 , and a modulus of elasticity of the third layer ( 30 ) is defined as E 3 , a definition of E 2 >E 1 >E 3 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. |
