PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell stack which can prevent the occurrence of cracks due to warpage of a separator in a solid oxide fuel cell, and to provide a method for manufacturing the solid oxide fuel cell stack.SOLUTION: The solid oxide fuel cell stack comprises: a first fuel battery cell laminate; a second fuel battery cell laminate; and a separator for radiation, which is provided between the first fuel battery cell laminate and the second fuel battery cell laminate. The first fuel battery cell laminate and the second fuel battery cell laminate have the solid oxide fuel cells and separators for connection, which are alternately stacked. A thickness of the separator for radiation is thicker than a thickness of the separator for connection. The method for manufacturing the solid oxide fuel cell stack is also disclosed.
