摘要 |
<p>There is provided a film having resistance to an increase in the friction coefficient resulting from wearing. The film has a first portion having hardness of 0.01 to 3 GPa and a second portion. The hardness ratio of the second portion to the first portion is of 1.2 to 30. The first portion and the second portion form a first surface portion and a second surface region of the film, respectively. Each of the first portion and the second portion extends to a depth of 75% or more of the thickness of the film. In a 1 mm×1 mm square region disposed on an arbitrary position of the surface of the film, the second surface region accounts for 10% to 80% by area of the square region, and the first surface region and the second surface region account for 50% or more by area of the square region.</p> |
