Patent ID: 7795592

Claim:
An image detector, comprising the following layers arranged on top of another: a charge generation layer that generates charges when exposed to a recording electromagnetic wave representing image information; and a charge detection layer that includes multitudes of detection elements disposed two-dimensionally, each having a switch element and a pixel electrode used for reading out the charges generated in the charge generation layer; wherein a smoothing layer formed by a wet coating process is provided between the charge generation layer and charge detection layer, wherein the smoothing layer is formed in such a manner as to satisfy Formula (1) below: θ1/θ2≦0.9 (1) where, θ1 is equal to 90 degrees minus an inclination of a side face of an outer edge portion of the pixel electrode with respect to the surface on which the pixel electrode is provided, and θ2 is equal to 90 degrees minus an inclination of a tilted face of the smoothing layer, wherein the smoothing layer is a blocking layer that has carrier selectivity.
