Abstract
A waterproof structure for a wire harness having at least one instrument, a plurality of electric wires connected thereto and a plurality of wire connecting parts at which the electrical wires are bundled. The waterproof structure includes a sealant having a viscidity less than 40000 CPS. The sealant is retained by the wire connecting part arranged in the nearest position to the instrument positioned at a tail end in an intruding course of water into the wire harness. Due to its low viscidity, the sealant can be brought easiliy among core lines constituting the wire, whereby gaps among the core lines can be sealed perfectly. Therefore, even if the water intrudes along the core lines through the other wire connecting parts, the flow of water can be checked at the specified wire connecting part thereby to protect the instrument from the immersion of water.
