In this work, thermal boundary conditions around thin platinum wire under the current supply were investigated. Thin Pt wires having various diameters were prepared and the currents required to cut the wires with Joule heating were investigated under the various intervals for current supply. An index describing the thermal boundary conditions around the wire quantitatively was introduced and the values of the index determined from the current to cut the wires were compared. Finally, the thermal boundary conditions around the wire having arbitrary diameter was able to be predictable.
