Transfer film, laminate, acoustic speaker, and method for producing laminate

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,

• 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, and
• the laminate comprises a third refractive index-adjusting layer exhibiting a higher refractive index than the refractive index of the resin layer between the first refractive index-adjusting layer and the resin layer.
