PROBLEM TO BE SOLVED: To attain a gamma ray camera that has an energy resolution power with a simple configuration.SOLUTION: A gamma ray camera 10 according to an embodiment has: a gamma ray split unit 15 that causes an incidence gamma ray incident from a gamma ray source 1 to be refracted, and divides the incidence gamma ray into a high energy gamma ray 4 higher in an energy than a boundary energy and a low energy gamma ray 3 refracting in an opposite direction of the high energy gamma ray 4 and lower in the energy than the boundary energy; a gamma ray detection unit 11a that can detect the gamma ray with the high energy gamma ray 4 and the low energy gamma ray 3 separated; and a gamma ray convergence unit 18 that lies between the gamma ray split unit 15 and the gamma ray detection unit 11a, and converges the high energy gamma ray 4 or low energy gamma ray 3 passing through the gamma split unit 15 on a different position in an installation range of the gamma ray detection unit 11a, respectively.SELECTED DRAWING: Figure 1 【課題】単純な構成でエネルギー分解能を持ったガンマ線カメラを実現する。【解決手段】実施形態によるガンマ線カメラ１０は、ガンマ線源１より入射する入射ガンマ線を屈折させ境界エネルギーより高いエネルギーの高エネルギーガンマ線４と高エネルギーガンマ線４と逆方向に屈折する境界エネルギーより低いエネルギーの低エネルギーガンマ線３とに区分するガンマ線分光部１５と、高エネルギーガンマ線４および低エネルギーガンマ線３を分離して検出可能なガンマ線検出部１１ａと、ガンマ線分光部１５とガンマ線検出部１１ａの間にあってガンマ線分光部１５を透過した高エネルギーガンマ線４または低エネルギーガンマ線３をそれぞれガンマ線検出部１１ａの設置範囲内の異なる位置に集光させるガンマ線集光部１８とを有する。【選択図】図１
