A thermo-electric power generating element has the structure that two kinds of metal sheets, or foils, which form a thermocouple combination are laminated together and alternately connected at one end and the other end so as to form a plurality of thermocouples connected in series. When hot junctions are held at a high temperature, a temperature gap along the thermal flux is generated in the sheets, or foils. Electromotive force at every thermocouple derived from the temperature gap is summed up to a voltage level effective for outputting electric power through takeoff leads. This power generator is useful for converting waste heat to electric power. When the thermocouple pile is made from corrugated sheets, or foils, electric power is outputted with high efficiency.

A conductive high molecular composition which comprises a non-conductive polymer component incorporated with a metal salt, characterized in that the metal salt is a salt of a metal with an acid substance selected from an organic carboxylic acid, rosin and a rosin derivative. This composition has an insulating property in normal state but functions as an electroconductive material only in the event it is interposed between slightly spaced metals and heated. Thus, the composition can be used not only as an insulating binder but also for imparting conductivity only in the desired spots of electronic parts, keeping the other areas of the parts electrically insulated. The composition thus possessing a specific dual function is particularly useful in the field of electronic industry.

A method for forming a metal film on the surface of a substrate metal, which comprises soaking a substrate metal or a non-metal support carrying the substrate metal thereon in a solution of a metal salt in a high boiling point solvent under heating conditions, characterized in that the metal salt is a salt of the metal to be formed on the surface of the substrate metal with an acidic substance selected from an organic carboxylic acid, a rosin and a rosin derivative. The metal is precipitated from the solution exclusively on the surface of the substrate metal without forming any solid metal particle in the solution or on the substrate metal. Thus, the method is applicable to the formation of a soldering alloy as a film on the surface of a substrate metal without leaving thereon any free metal particle which may cause short circuits in electronic circuits. The method can thus be applied advantageously to the manufacture of electronic elements having a metal film thereon and high density printed circuits, and thus is also useful in the field of electronic industry.

A conductive high molecular composition which comprises a non-conductive polymer component incorporated with a metal salt, characterized in that the melt salt is a salt of a metal with an acid substance selected from an organic carboxylic acid, rosin and a rosin derivative. This composition has an insulating property in the normal state but functions as an electroconductive material only in the event it is interposed between slightly spaced metals and heated. Thus, the composition can be used not only as an insulating binder but also for imparting conductivity only in the desired spots of electronic parts, keeping the other areas of the parts electrically insulated.
