Electrically insulated cable and harness integrated with sensor

An electrically insulated cable comprising:

• a plurality of coated electric wires and a sheath covering outer peripheries of the plurality of coated electric wires,
• wherein an average value of surface roughness Rz of an outer surface of the sheath is 15 μm or more and 75 μm or less,
• wherein when a peel test is performed on a fusion strength evaluation sample obtained by thermally fusing the outer surface of the sheath separated from the plurality of coated electric wires to a sheet of polybutylene terephthalate, a maximum peel strength is converted to a value per 1 cm of a width of a fusion surface between the sheath and the sheet of polybutylene terephthalate included in the fusion strength evaluation sample and the value is defined as a fusion strength of the sheath, and
• wherein the fusion strength of the sheath is 50 N/cm or more.
