A thermoelectric cooler includes a plurality of P-type semiconductor elements, a plurality of N-type semiconductor elements, a plurality of connection circuits, a cold end and a hot end. The P-type semiconductor elements are electrically connected to the N-type semiconductor elements by the connection circuits. The P-type semiconductor elements, the N-type semiconductor elements and the connection circuits are sandwiched between the cold end and the hot end providing thermal connection therebetween. The cold end includes a first metal base and a first insulated metal oxide film formed on a side of the first metal base adjacent to the P-type semiconductor elements, the N-type semiconductor elements and the connection circuits.
