In this paper, the manipulation technique for very-thin metallic wires based on Joule heat joining is reported. Our basic idea is to weld the objective thin wires on substrate material, which can easily be manipulated. Thick In wires were selected as substrates, and very-thin Pt wires with the diameter of 650 nm were welded onto In wire substrate by Joule heating. The Pt wire on the In substrate was undertaken for small-span bending test and the mechanical properties, especially Young's modulus and the yield strength of the wire were successfully determined. For electrical properties, the electrical circuits including the thin Pt wire were fabricated on an electrode chip, and the potential drops using two Ag probes for various probe distances were measured. The electrical resistivity of the Pt wire was successfully evaluated from the measured potential drop data.
