Abstract

A solid electrolyte is constituted by lithium phosphorus oxynitride (LiPON). A multiplication value obtained by multiplying a ratio of a peak intensity of nitrogen atoms having a single bond with one P atom and having a double bond with another P atom to a peak intensity of an Nstate in a Raman spectroscopy spectrum by a ratio of a content amount of N atoms to a content amount of P atoms is greater than or equal to 0.40.
