PROBLEM TO BE SOLVED : To provide the air electrode collector material of a solid oxide fuel cell which is essential to have high electrical conductivity to lower a collector loss and that is compatible with the coefficient of thermal expansion consistent as the equivalent value of an electrolytic material. SOLUTION : The air electrode collector material is expressed in a general formula as ABO3. The symbol A corresponds to more than one element selected from among a group of La, rare-earth element, and alkali earth metal; and the symbol B is a composite material of a dope ceria powder and a perovskite compound oxidized powder comprising more than one element selected from a group of Co, Fe, Ni and Cu. More specifically, the perovskite compound oxidized powder is a lanthanium-strontium-cobalt oxide (LSC) powder, the dope ceria powder is a gadrinium-dope ceria (GDC) powder, and a volume ratio preferably lies in the range of 7 : 3 to 4 : 6 in the perovskite compound oxidized powder and the dope ceria powder.
