Abstract
The present invention provides a radiation detector that can suppress a deterioration of image quality of a radiation image while suppressing the size of the radiation detector. Namely, a conductive layer configured by a conductive member is disposed at a portion that corresponds to at least the back side of the peripheral edge portion of a bias electrode, on the surface of an insulating substrate.
Claims8
A radiation detector comprising:
- a substrate formed in a flat plate form and having a first surface provided with an insulating property;
- a plurality of collecting electrodes, disposed on the first surface of the substrate, that collects charges;
- a semiconductor layer, formed on the plurality of collecting electrodes, that generates charges when radiation is irradiated;
- a bias electrode, formed on the semiconductor layer, that applies a bias voltage for generating an electric field for moving charges having a polarity of a detection target among the generated charges, to the collecting electrodes;
- and
- a conductive layer, composed of a conductive member, disposed on a second surface of the substrate at a portion corresponding to a peripheral edge portion of the bias electrode.
