Abstract: An adhesive sheet capable of bonding adhesive layers together at normal temperatures, with little stickiness of the adhesive layers due to a plasticizer seeping out from a substrate providing a protective material using the adhesive sheet and a wire harness. An adhesive sheet including: a substrate containing 20-100 parts by mass of a polyester-based plasticizer to 100 parts by mass of a vinyl halide-based resin; a primer layer; adhesive layers included amount of a tackifier is 0-250 parts by mass and the inorganic microparticles is 0-250 parts by mass to 100 parts by mass of an elastomer, and a total value of the included amounts of the tackifier and the inorganic microparticles is 0-350 parts by mass; wherein the adhesive layers probe tack of 7 N/cm2 or less with ASTM D 2979, and the adhesive force between the adhesive layers width of 15 mm is 1.5 N or more.

Abstract: An adhesive sheet including a substrate and adhesive layers that are arranged on one surface of the substrate with a primer layer being interposed therebetween, wherein the adhesive layers include a natural rubber and a tackifier, the adhesive sheet has a volume resistivity of 1×1010? cm or more and a tensile modulus at 100% elongation of 50 MPa or less as determined in accordance with JIS K 6251, the adhesive layers have a probe tack of 10N/cm2 or less as determined in accordance with ASTM D 2979, the adhesive force between the adhesive layers having a width of 15 mm is 1.5 N or more, and the adhesive force between the substrate and the adhesive layers having a width of 15 mm is 1.5 N or less.
