Abstract
Provided is a radiation detector having a portion in which a substrate in which a plurality of pixels for accumulating electric charges generated in accordance with light converted from radiation are formed in a pixel region, a conversion layer that converts radiation into light, a reflective pressure sensitive adhesive layer that reflects the light converted by the conversion layer, and an adhesive layer that covering a region including a region ranging from an end part of the pressure sensitive adhesive layer to a surface of the substrate are provided in this order.

A radiation detector comprising a portion in which
- a substrate in which a plurality of pixels for accumulating electric charges generated in accordance with light converted from radiation are formed in a pixel region,
- a conversion layer that converts the radiation into light,
- a reflective pressure sensitive adhesive layer that reflects the light converted by the conversion layer,
- an adhesive layer that covers a region including a region ranging from an end part of the pressure sensitive adhesive layer to a surface of the substrate
- are provided in this order
- wherein the conversion layer includes a peripheral edge part and a central region, the peripheral edge part having an inclination such that a thickness of the conversion layer decreases toward an outer side, and
- wherein the adhesive layer covers the entire central region of the conversion layer and a portion of the peripheral edge part of the conversion layer, and the end part of the pressure sensitive adhesive layer is located at the peripheral edge part of the conversion layer.
