<P>PROBLEM TO BE SOLVED: To provide an interconnector for a solid oxide fuel cell with a low resistance value and hardly generating peeling between the interconnector and an electrode. <P>SOLUTION: The interconnector for a solid oxide fuel cell 3 is provided with a first metal oxide film 2 made of perovskite metal oxide typically represented by the general formula La<SB>(1-a)</SB>M<SP>1</SP><SB>(a)</SB>M<SP>2</SP>O<SB>3</SB>coated on one surface of a Cr-containing alloy base material 1, with a film thickness of the first metal oxide film to be 5.0 to 30 μm, and a surface roughness Ra of the first metal oxide film to be 0.5 to 3.0 μm, (in the formula, M<SP>1</SP>is one or two kinds or more selected from Ca, Sr and Ba, M<SP>2</SP>is one or two kinds or more selected from Cr, Mn, Fe, Co and Ni, and 0≤a≤0.3 is satisfied). <P>COPYRIGHT: (C)2010,JPO&INPIT |
