摘要：
A solid electrolyte cell includes: a positive electrode side layer having a positive electrode active material layer; a negative electrode side layer; and a solid electrolyte layer formed between the positive electrode side layer and the negative electrode side layer, wherein the positive electrode active material layer contains a lithium phosphoric acid compound which is in an amorphous state and is represented by the following formula (1), LixCuyPO4 (1) where x indicates the compositional ratio of lithium, and y indicates the compositional ratio of copper, x and y being in the ranges of 1.0≦x≦5.0 and 1.0≦y≦4.0, respectively.
