Solid state radiation detector

A solid state radiation detector comprising a set of layers layered in the order of:

• a first conductive layer which is transparent to recording light;
• a recording photoconductive layer that shows photoconductivity when exposed to recording light;
• a storage section that stores charges as latent image charges in accordance with the luminous energy of recording light;
• a reading photoconductive layer that shows photoconductivity when exposed to reading light;
• and
• a second conductive layer having a plurality of charge detecting linear electrodes, and a plurality of auxiliary linear electrodes,
• wherein:
• when viewed from the layering direction, a region having a predetermined width extending inwardly from the outer edge of the first conductive layer is defined as the non-image-detection area, and a region other than the non-image-detection area of the first conductive layer is defined as the image detection area;
• the charge detecting linear electrodes and auxiliary linear electrodes are disposed alternately in the image detection area;
• and
• the charge detecting linear electrode partly lying in the image detection area is formed such that the width in the non-image-detection area or in the region adjacent to the outer edge of the first conductive layer is greater than in the image detection area.
