1. A radiation detector comprising:
a sensor panel;
a scintillator panel; and
a resin frame provided across the sensor panel and the scintillator panel, wherein
the sensor panel has a mounting surface where the scintillator panel is mounted,
the scintillator panel includes
a support body having a first surface, a second surface on a side opposite to the first surface, and a first side surface connecting the first surface and the second surface to each other, and
a scintillator layer formed on the first surface and containing a plurality of columnar crystals,
the scintillator panel is mounted on the mounting surface such that the scintillator layer and the first surface face the mounting surface,
the scintillator layer has a second side surface extending so as to be positioned on the same plane as the first side surface,
the resin frame is configured to seal the scintillator layer by extending at least from the mounting surface onto the first side surface when viewed in a first direction intersecting with the first side surface and the second side surface, and
the resin frame extends from the mounting surface to a peripheral edge portion of the second surface.
