The resin frame has a groove continuous with an outer edge of the protective film. The groove includes a pre-irradiation portion formed by performing scanning along the resin frame while increasing the energy of a laser beam, a main irradiation portion formed by performing scanning along the resin frame while maintaining the energy of the laser beam, and a post-irradiation portion formed by performing scanning along the resin frame while decreasing the energy of the laser beam.

Abstract: A radiation detector includes: a light detection panel that has a light-receiving unit, and a bonding pad that is electrically connected to the light-receiving unit; a scintillator layer that is provided on the light detection panel to cover the light-receiving unit; and a protective layer that is provided on the light detection panel to cover the scintillator layer. An outer edge portion of the protective layer has an adhesive portion that is in close contact with the light detection panel in a region between the scintillator layer and the bonding pad, and an extension that extends from the adhesive portion to an opposite side of the light detection panel in a self-supporting state.

Abstract: A radiation detector includes a signal readout substrate. The signal readout substrate is constructed by arranging pixel units having pixel electrodes in a two-dimensional matrix form on a front surface of a substrate. On a front surface of the signal readout substrate, formed is a photoconductive layer having crystallinity. On a front surface of the photoconductive layer, formed is a contact assistance layer having conductivity. On a front surface of the contact assistance layer, formed is a common electrode. A surface area per unit region of the front surface of the contact assistance layer is smaller than a surface area per unit region of the front surface of the photoconductive layer. In addition, the contact assistance layer is formed so as to include the common electrode and so as to be included in the front surface of the photoconductive layer when viewed from the front.

Abstract: Not only is a common electrode suppressed from having a high resistance, but the common electrode is also prevented from peeling. A radiation detector 1 includes a signal readout substrate 2. The signal readout substrate 2 is constructed by arranging pixel units 4 having pixel electrodes 7 in a two-dimensional matrix form on a front surface 3a of a substrate 3. On a front surface 2a of the signal readout substrate 2, formed is a photoconductive layer 17 having crystallinity. On a front surface 17a of the photoconductive layer 17, formed is a contact assistance layer 30 having conductivity. On a front surface 30a of the contact assistance layer 30, formed is a common electrode 18. A surface area per unit region of the front surface 30a of the contact assistance layer 30 is smaller than a surface area per unit region of the front surface 17a of the photoconductive layer 17.
