Abstract

A thermoelectric module 1 comprising p-type thermoelectric elements 3a and n-type thermoelectric elements 3b which are alternately arranged and electrically connected by electrodes 4 provided on the top side and the bottom side of each thermoelectric element 3 and a heat exchanger plate 5 which is fixed on the electrodes on each side, in which each thermoelectric element 3 has a coating film 2 of an insulating material on the sides thereof except the sides joined to the electrodes 4, and the thermoelectric elements 3 are spaced apart. The coating film 2 improves the strength and moisture resistance of the thermoelectric elements 3 to prevent thermoelectric elements from cracking or breaking even in cases where a load, a shock, or a thermal stress is imposed thereon and to protect the thermoelectric elements against corrosion in a high humidity atmosphere, providing a thermoelectric module 1 with improved operational reliability.
