1. A radiation detector comprising:
a sensor panel having a light receiving surface;
a first scintillator panel and a second scintillator panel disposed on the light receiving surface in a state of being adjacent to each other along the light receiving surface; and
an adhesive layer disposed between the light receiving surface and the first scintillator panel and between the light receiving surface and the second scintillator panel, wherein
the first scintillator panel has a first substrate and a first scintillator layer including a plurality of columnar crystals formed on the first substrate,
the second scintillator panel has a second substrate and a second scintillator layer including a plurality of columnar crystals formed on the second substrate,
the first scintillator panel is attached to the light receiving surface by the adhesive layer in a state where the first scintillator layer is positioned on the light receiving surface side with respect to the first substrate,
the second scintillator panel is attached to the light receiving surface by the adhesive layer in a state where the second scintillator layer is positioned on the light receiving surface side with respect to the second substrate,
an outer edge of the first substrate when viewed from the first scintillator layer side includes a first portion extending along the second scintillator panel, and the first scintillator layer reaches at least the first portion,
an outer edge of the second substrate when viewed from the second scintillator layer side includes a second portion extending along the first scintillator panel, and the second scintillator layer reaches at least the second portion, and
the adhesive layer is separated for each of the first scintillator panel and the second scintillator panel.
