Conducting polypyrrole films were electrochemically prepared from aqueous solution containing sodium p-toluenesulphonate as supporting electrolyte at constant current density. The films produced have electrical conductivities of about 35.8 S/cm. Seebeck effect was observed in all three junctions formed by polypyrrole with aluminum, copper and stainless steel. The maximum Seebeck coefficient obtained is from polypyrole/A1 junctions, which is about 33.3uV/C
