Provided are a conductive sintered body, a fuel cell conductive member, a fuel cell, and a fuel cell that can effectively suppress reductive expansion. A conductive sintered body containing a lanthanum chromite-based first composite oxide phase 59 and a second composite oxide phase 55 of Mg and Ni, and surroundings of the second composite oxide phase 55 Ni57 is deposited on the surface. Such a conductive sintered body is used for a fuel cell. Further, such a conductive member for a fuel cell includes an interconnector 35 of a fuel cell 30 in which a solid electrolyte layer 33 is sandwiched between electrode layers 32 and 34 and an interconnector 35 connected to the electrode layer 32 is provided. 35 is used.
