SOLID ELECTROLYTE, MANUFACTURING METHOD THEREOF, PROTON CONDUCTION BODY, AND SCREENING DEVICE
To provide a novel solid electrolyte which can be actuated in middle and low temperature ranges and has proton conductivity.SOLUTION: The present invention relates to a solid electrolyte having a non-perovskite crystal structure containing a mother crystal containing an oxygen element and a first metal element as constituent elements and a second metal element which is solid-solved on the mother crystal and of which the valence is smaller than that of the first metal element. In the solid electrolyte, a minimum value of hydration energy, which is calculated based on first principle calculation, in a plurality of proton sites on a proton conduction path that the mother crystal includes is -3.0 eV or more and -0.5 eV or less, a maximum value of a difference of the hydration energy is 0.5 eV or less and solid solution energy of the second metal element, which is calculated by the first principle calculation, with respect to the mother crystal is 1.3 eV or less.SELECTED DRAWING: None
