Radiation detector and radiography apparatus having the same

A radiation detector, comprising:

• a housing;
• a radiation detection panel accommodated in the housing and converting radiation incident from the outside of the housing into an electric signal;
• a printed circuit board electrically connected to the radiation detection panel;
• and
• an intermediate plate that is disposed between the radiation detection panel and the printed circuit board, supports the radiation detection panel, and is electrically connected to a ground line of the printed circuit board,
• wherein the intermediate plate comprises a base plate and an electrically conductive first metal layer that is formed in a shape of a blanket film and is electrically connected to the ground line of the printed circuit board, and
• the intermediate plate is transmissive to the radiation, and is formed as a conductive plate, and
• wherein the radiation is uniformly reflected over the surface of the intermediate plate by the first metal layer.
