PURPOSE: A bimetal structure of a self-electric generator is provided to uniformly maintain the operating point of a bimetal. CONSTITUTION: A bimetal structure of a self-electric generator comprises a first metal(201), a second metal(203), and a third metal(205). The first metal constituting the outermost shell is molded to have low thermal expansion coefficient using nickel-iron alloy. The second metal constituting the innermost shell is molded to have high thermal expansion coefficient using nickel-molybdenum-iron alloy. The third metal is molded using the alloy of nickel, copper, magnesium, and niobium. One end of the bimetal structure has an opened elliptic shape.
