What is claimed is: 1 . An electrochemical device, comprising: an electrolyte membrane; an anode disposed on a first main surface of the electrolyte membrane; a cathode disposed on a second main surface of the electrolyte membrane; an anode separator disposed on the anode; and a cathode separator disposed on the cathode, wherein at least one of the anode separator or the cathode separator includes a metal substrate sheet and a conductive layer disposed on the metal substrate sheet and containing a metal oxide and a metal hydroxide. 2 . The electrochemical device according to claim 1 , wherein the metal hydroxide is produced by introducing protons to a metal oxide-containing layer. 3 . The electrochemical device according to claim 1 , wherein the metal oxide is chromium oxide, and the metal hydroxide is chromium hydroxide. 4 . The electrochemical device according to claim 1 , wherein the metal substrate sheet is made of stainless steel. 5 . The electrochemical device according to claim 4 , wherein the metal substrate sheet is made of SUS316 or SUS316L. 6 . The electrochemical device according to claim 4 , wherein the metal substrate sheet is made of 4401-316-00-I or 4436-316-00-I, or 4404-316-03-I, 4432-316-03-I, or 4436-316-91-I. 7 . The electrochemical device according to claim 4 , wherein the metal substrate sheet is made of 1.4401 or 1.4436, or 1.4404, 1.4432, or 1.4435. 8 . The electrochemical device according to claim 4 , wherein the metal substrate sheet is made of S31600 or S31603. 9 . The electrochemical device according to claim 4 , wherein the metal substrate sheet is made of S31608 or S31603. 10 . The electrochemical device according to claim 1 , wherein the conductive layer has a thickness more than or equal to 0.001 μm and less than or equal to 5 μm. 11 . The electrochemical device according to claim 1 , wherein the conductive layer contains at least one of fluorine at a fluorine concentration of 0.1 atom % or more or lithium at a lithium concentration of 0.01 atom % or more.
