Abstract
A water repellent film () according to the present invention includes a first layer () having a plurality of fine protrusions () on the surface thereof, a second layer () covering the fine protrusions () and having a water repellent property, and a third layer () provided on the surface of the first layer () on the opposite side of the fine protrusions (). When a modulus of elasticity of the first layer () is defined as E, a modulus of elasticity of the second layer () is defined as E, and a modulus of elasticity of the third layer () is defined as E, a definition of E>E>Eis 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.
