PROBLEM TO BE SOLVED: To provide a manufacturing method wherein bonding strength of electrodes and thermoelectric elements is improved and change of thermoelectric module size is easy, in a thermoelectric module wherein P type thermoelectric elements and N type thermoelectric elements are adjacently arranged to each other, both end surfaces of the aligned thermoelectric elements are connected by using conductive electrodes, and heat exchanging boards are fixed on both of the electrode surfaces. SOLUTION: A billet capsule 7 wherein a filling hole 8 is arranged in the longitudinal direction of a stick member is formed. The filling hole 8 is filled with P-type thermoelectric elements 6a and N-type thermoelectric element 6b in the state that they are made adjacent to each other. The billet capsule 7 is stretched by extrusion working, and an extrusion work capsule is formed. This extrusion work capsule is cut so as to cross the longitudinal direction, and a plurality of plate members 12 are formed. Conductive electrodes 2 are formed on both of the cut surfaces of the plate members 12. Heat exchanging boards are fixed on the electrode surfaces, and a thermoelectric module is manufactured.
