MULTI-ELECTRODE PROBE

PURPOSE: To prevent wrong wiring of a band-shaped parallel wire comprising a plurality of signal line groups of a multi-electrode probe, to prevent disconnection in each strand of the band-shaped parallel wire, the slackening of a winding and changes in outer diameter and to achieve a finger diameter and a less thickness of the multi-electrode probe. CONSTITUTION: A colored insulating layer 4 and a fused layer 5 are formed on each strand of signal line 2 groups composing electrodes of a multi-electrode probe. A band-shaped parallel wire unit is made up of the signal wire 2 groups to array a plurality of fundamental color units.
