Radiographic image detector, method of producing the same, and protective member

1. A method of producing a radiographic image detector, the method comprising:

preparing a thin-film transistor substrate comprising an insulating substrate and a thin-film transistor that is disposed on a surface of the insulating substrate at a first side;

attaching, to the thin-film transistor substrate, a protective member comprising a protective member support and an adhesive layer that includes conductive particles and that is disposed on the protective member support, such that the adhesive layer and a surface of the thin-film transistor substrate at the first side contact each other;

polishing a surface of the thin-film transistor substrate at a second side opposite to the first side, after the attaching of the protective member;

separating and removing the protective member from the thin-film transistor substrate after the polishing; and

providing a scintillator layer on a surface of the thin-film transistor substrate at the first side, after the removing of the protective member,

wherein the content of the conductive particles in the adhesive layer is from 0.1% by mass to 40% by mass relative to the total mass of the adhesive layer.

2. The method of producing a radiographic image detector according to claim 1 , wherein the conductive particles are carbon particles.

3. The method of producing a radiographic image detector according to claim 1 , wherein the number average particle diameter of the conductive particles is from 0.01 μm to 50 μm.

4. The method of producing a radiographic image detector according to claim 1 , wherein the adhesive layer further comprises thermally-expandable particles.

5. The method of producing a radiographic image detector according to claim 1 , further comprising adhering a support member to a surface of the thin-film transistor substrate at the second side, after the polishing but before the removing of the protective member.

6. The method of producing a radiographic image detector according to claim 1 , wherein the scintillator layer comprises a crystal including CsI, or a crystal including Gd 2 O 2 S and Tb.

7. The method of producing a radiographic image detector according to claim 1 , wherein the conductive particles are contained inside the adhesive layer.

8. A radiographic image detector which is produced by the method of producing a radiographic image detector according to claim 1 , wherein the radiographic image detector detects a radiographic image by allowing a radiation to be incident from the second side of the thin-film transistor substrate.
