Minute protrusions are formed on the surface of the outer resin layer or the inner resin layer, and the minute protrusion structure has a fractal dimension of 1.08 to 1.17, wherein the fractal dimension is a numeric value calculated by the box count method at a resolution at which the length per one pixel is 0.5-1.0 μm.
