Abstract
A waterproofing structure for shielded cable includes: a shielded cable including one or more cables and a braided wire serving as a shielding member and covering the cables; a grommet serving as a waterproofing member and covering a waterproofed portion on the braided wire; and a heat shrinkable tube including an adhesive disposed to cover the waterproofed portion of the braided wire 13. The adhesive pushed into the braided wire by heat shrinkage of the heat shrinkable tube fills a gap between a plurality of strands of the braided wire in an entire region of the waterproofed portion and a gap between the cable and the braided wire. A space between an outer circumferential surface of the heat shrinkable tube and a part of an inner circumferential surface of the waterproofing member is blocked without any gap in a circumferential direction.
