PROBLEM TO BE SOLVED: To provide a thermoelectric material, thermoelectric conversion element, and multilayer thermoelectric conversion system, capable of recovering chemical energy and waste heat energy at the same time. SOLUTION: The thermoelectric material is a crystalline oxide consisting of iron, cobalt, nickel, barium, and strontium, and has a composition of AFe<SB>1-y</SB>B<SB>y</SB>O<SB>3</SB>or A<SB>4</SB>Fe<SB>6-x</SB>B<SB>x</SB>O<SB>13</SB>(A=Sr, Ba, otherwise, Sr:Ba=1:1, B=Co, Ni, x=0.0-0.8), providing thermoelectric electromotive force. A multilayer thermoelectric conversion element has a multilayer consisting of a layer of thermoelectric material and a layer of ceramic oxide which shows ion conductivity or electron conductivity. A multilayer thermoelectric conversion system is also disclosed. COPYRIGHT: (C)2008,JPO&INPIT
