PROBLEM TO BE SOLVED: To provide a shielded electric wire capable of satisfying target values of both abrasion properties and shielding properties, and a wire harness.SOLUTION: A shielded electric wire 1 includes: a metallic foil member 4 that forms a shielding layer by covering a periphery of the electric wire 2, 3; a sheet-shaped member 5 that covers a periphery of the metallic foil member; and a protective tape 6 spirally wound on a periphery of the sheet-shaped member 5. The sheet-shaped member 5 includes a first sheet material 5a and a second sheet material 5b. One surface of the first and second sheet materials 5a, 5b is formed with an adhesive layer 7a, 7b, respectively. The first and second sheet materials have a width Lw longer than a half circumferential distance Lh of the metallic foil member 4 provided on the periphery of the electric wire 2, 3, and are stuck on the metallic foil member 4 from sides thereof respectively facing the metallic foil member 4. The adhesive layers 7a, 7b are opposingly stuck in extra length portions 8a, 8b protruding in a width direction.SELECTED DRAWING: Figure 3
