Radiation detector manufacturing method, radiation detector, radiation imaging apparatus, and radiation imaging system

Abstract

A radiation detector manufacturing method is provided. The method includes: preparing a structure including a support base, a flexible base member arranged on the support base and having a principal surface including a pixel region in which a plurality of pixels are arranged, a scintillator arranged so as to cover the pixel region, and a protective layer arranged so as to cover the scintillator; and removing the support base from the flexible base member. The principal surface includes a peripheral region not covered with the protective layer. The method further includes, before the removing, arranging a reinforcing member in contact with the peripheral region, in a position overlapping the peripheral region and not overlapping the scintillator, in orthogonal projection to the principal surface.
