Disclosed is a thermoelectric device in which a separate interlayer is inserted between a thermoelectric leg and an electrode to reduce the contact resistance between the thermoelectric leg and the electrode, so that the interlayer serves as a tunneling path between the thermoelectric leg and the electrode, facilitating the charge movements between the two materials. The thermoelectric device according to an embodiment includes a substrate; at least one thermoelectric leg positioned on the substrate; an interlayer positioned on each thermoelectric leg of the at least one thermoelectric leg and including a plurality of interlayer materials that are chemically bonded with a respective thermoelectric leg; and an electrode positioned on each interlayer and electrically connected to the respective thermoelectric leg, wherein the plurality of interlayer materials of each respective interlayer is arranged in a shape of a brush.
