1. A laminate comprising, in the following order:
a substrate;
a layer with a high refractive index;
a second refractive index-adjusting layer;
a resin layer; and
a first refractive index-adjusting layer,
wherein a refractive index of the layer with a high refractive index is higher than a refractive index of the resin layer,
the second refractive index-adjusting layer exhibits a higher refractive index than the refractive index of the resin layer and a lower refractive index than the refractive index of the layer with a high refractive index,
a refractive index of the first refractive index-adjusting layer is lower than the refractive index of the resin layer,
the refractive index of the first refractive index-adjusting layer is 1.45 or less,
the layer with a high refractive index is a transparent conductive layer,
the laminate comprises a fourth refractive index-adjusting layer on a side opposite to the resin layer side of the second refractive index-adjusting layer, and
the fourth refractive index-adjusting layer exhibits a lower refractive index than the refractive index of the resin layer.
