Abstract
A proton conductor includes a main constituent element. A part of the main constituent element is substituted by a transition metal. Valence of the transition metal is variable between valence of the main constituent element and valence lower than the valence of the main constituent element.

A method of manufacturing an electrolyte for a proton conductive type fuel cell comprising a generation step of generating the electrolyte under an oxidation condition in which oxygen partial pressure is 0.01 atm or higher,
- a part of a main constituent element of the electrolyte being substituted by a transition metal,
- valence of the transition metal being variable between a first valence that is the same as that of the main constituent element and a second valence that is lower than the first valence,
- the oxidation condition being a condition in which the valence of the transition metal is a value more than the second valence and less than the first valence.
