1. A touch panel module, comprising:
- wherein a conductive film in which a mesh conductive layer composed of a mesh-like metal electrode is formed on a support, a first λ
/4 plate, a polarizing plate, and a protective layer are arranged in this order,a second λ
/4 plate is further arranged on a side of the conductive film opposite to the protective layer,a visible light diffuse reflectivity measured from the protective layer is 0.09% or more and 0.2% or less, andthe support has a retardation value of 40 nm or less at a wavelength of 550 nm in an in-plane direction.

Abstract
A touch panel module in which a conductive film in which a mesh conductive layer composed of a mesh-like metal electrode is formed on a support, a λ/4 plate, a polarizing plate, and a protective layer are arranged in this order. A λ/4 plate is further arranged on a side of the conductive film opposite to the protective layer. The touch panel module has a visible light diffuse reflectivity of 2% or less, which is measured from the protective layer.
