A proton conductor is provided. The proton conductor includes a zwitterion salt such as MeImPrSO<SUB>3 </SUB>and a proton (H<SUP>+</SUP>) donor such as HTFSI. An electrochemical device having a stacked layer structure formed of a first electrode, a second electrode and a proton conducting layer held between these electrodes, wherein the proton conducting layer includes a proton conductor according to the present invention. The present invention can, therefore, provide a proton conductor and electrochemical device, which can be suitably used in a dry state or under high-temperature, non-humidified conditions, can obviate a complex accessory such as a humidifier, and can simplify the system.
