<p><P>PROBLEM TO BE SOLVED: To provide a scintillator, along with a radiation detector and a manufacturing method of the scintillator, which can easily be manufactured for realizing a high positional resolution. <P>SOLUTION: A scintillator 1 includes a crystal body 2 which generates scintillation light upon incidence of radiation, and is used to provide the scintillation light to an optical detector coupled optically to a surface of the crystal body 2. The crystal body 2 is divided into a plurality of bodies. A division surface 3 formed at the crystal body 2 includes a plurality of reformed regions 4 formed by radiating laser beam into the inside of the crystal body 2, and a cutting surface 5 that is formed to connect between a plurality of reformed regions 4 by applying a stress to the crystal body 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
