A radiographic imaging apparatus 1 has a solid-state image sensor 11, a scintillator 21, and others. The solid-state image sensor 11 has a photosensitive section 13 and an amplification section 15, which are formed on one side of an Si substrate 12. The photosensitive section 13 includes a plurality of photodiodes 16 as photoelectric converters for photoelectric conversion, and these photodiodes 16 are arrayed in a two-dimensional pattern. The amplification section 15 amplifies outputs from the photodiodes 16 and outputs amplified signals. The scintillator 21 is arranged to cover a region where the photosensitive section 13 and the amplification section 15 are formed on the one side of Si substrate 12, and is formed directly on the region.
