Abstract
Provided is a radiation detecting element, including: needle crystal scintillators and a protruding pattern in which: one end of the needle crystal scintillators is in contact with of upper surfaces of the multiple protrusions; a gap corresponding to a gap between the multiple protrusions is provided between portions of the needle crystal scintillators in contact with the upper surfaces of the multiple protrusions; and a number of the needle crystal scintillators in contact with one of the upper surfaces is 5 or less. Conventionally, since the needle crystals exhibit a state of a polycrystalline film in an early stage of vapor deposition, and light also spreads in a horizontal direction, the light received by a photodetector portion and the spatial resolution was lower than ideal values. The present invention enables the deviating region to be the ideal state in an early stage of growth.
