To simplify and reduce the cost of a phase contrast radiation imaging apparatus that utilizes a Talbot interferometer. A phase contrast radiation imaging apparatus is includes a radiation source 11, a diffraction grating 30, and a radiation image detector 40. The radiation image detector 40 is equipped with a charge generating layer that generates electric charges when irradiated with radiation, and charge collecting electrodes that collect the electric charges. The charge collecting electrodes are linear electrode groups, constituted by linear electrodes which are arranged at a constant period and are electrically connected to each other, provided to have different phases from each other. Thereby, use of a conventional amplitude diffraction grating is obviated. |
