A medium region (S) is formed by filling a space between an outer tubular body (1a) and an inner tbular body (1b) with liquid xenon (2), and a pair of anode pads (11, 12) are arranged two-dimensionally at the opposite ends of the medium region (S) intersecting the incident direction of gamma rays. An intermediate electrode (10) is arranged between the pair of anode pads (11, 12) and a plurality of photomultipliers (5) are arranged two-dimensionally on the outer tubular body (1a). A gamma ray reaction point in the liquid region (S) is specified based on the signals outputted from the anode pads (11, 12) and the photomultipliers (5).
