Abstract: In a fuel cell unit 16 that constitutes a fuel cell module 2 of an SOFC device 1, a collector cap 86a is connected to an inner electrode layer 90 via a seal material 96 as an Ag seal portion. A glass coating 30 (dense body) is filled up between the inner electrode layer 90 and an electrolyte layer 94 and the collector cap 86a to cover an upper end surface 96a of the seal material 96. As such, the fuel cell unit 16 includes the seal material 96 constituting as an Ag seal portion that separates a fuel gas from an oxidant gas, and a glass coating 30 at least partially formed to over at least either the fuel gas side surface of the seal material 96 or an the oxidant gas side surface of the seal material 96.
