A scintillator panel is provided. The scintillator panel comprises: a support; a scintillator configured to generate light in accordance with incident radiation; a light reflecting layer arranged between the support and the scintillator and configured to reflect the light; a semi-transmissive layer arranged between the light reflecting layer and the scintillator and configured to reflect part of the light and transmit other part of the light; and an optical adjustment layer arranged between the light reflecting layer and the semi-transmissive layer and configured to make an optical distance between the light reflecting layer and the semi-transmissive layer become a length with which the light resonates.
