1. in the middle of a base material film, its for support patterned after conductive layer, wherein, this middle base material film possesses:

  • Transparent base;

    Lamination is in the 1st hyaline layer of the side of described transparent base, and refractive index is less than more than 1.47 1.57 and thickness is more than 1 μ

    m;

    1st high refractive index layer of lamination on described 1st hyaline layer, refractive index is less than more than 1.62 1.72 and thickness is more than 20nm below 80nm;

    With1st low-index layer of lamination on described 1st high refractive index layer, refractive index is less than more than 1.44 1.54 and thickness is more than 3nm below 45nm,If the normal to a surface direction of described middle base material film is 0 °

    , irradiate light by base material film in the middle of described in described 1st low-index layer side direction every 5 degree convert incident angle in the scope of less than 75 °

    more than 0 °

    while, obtain L by the respective reflected light towards normal reflection direction *a *b *the a of colorimeter system *value and b *during value, a *the fluctuation of value is within 1.0, and b *the fluctuation of value is within 1.6.
