A semiconductor radiation detector has a plurality of semiconductor cells for detecting radiation from a subject. These semiconductor cells include a plurality of voltage application electrodes and a plurality of signal read electrodes. The semiconductor cells are so arrayed that the cell array forms a concave shape and the semiconductor cells are parallel to each other. Since the semiconductor cells are arrayed to form a concave shape, not only semiconductor cells near the center but also semiconductor cells near the peripheries are located close to the subject. This increases the positional resolution and sensitivity. Since the semiconductor cells are arranged parallel to each other, collimated gamma rays always perpendicularly enter the incidence surface regardless of the incident position of the gamma rays. This equalizes the distances the gamma rays travel regardless of the incident positions, so the sensitivity is substantially constant regardless of the incident positions.
