To provide a technique capable of suppressing a mass increase in a wire harness in which an insulation coating of an electric wire and a sheet material are welded to each other.SOLUTION: A wire harness 10 includes: an electric wire 20 including a core wire 22 and an insulation coating 26 coating the core wire 22; and a sheet material 30 which has the electric wire 20 arranged on a resin main surface 33 and where in the main surface 33, a portion in contact with the electric wire 20 is welded to the insulating coating 30 of the electric wire 20 and is formed on an electric wire fixing part 34. A largest thickness dimension B in the electric wire fixing part 34 in the sheet material 30 is formed to be larger than thickness dimensions C and D in a portion where the electric wire 20 is not arranged in the sheet material 30.SELECTED DRAWING: Figure 2 【課題】電線の絶縁被覆とシート材とが溶着されたワイヤーハーネスにおける質量増加を抑制できる技術を提供することを目的とする。【解決手段】ワイヤーハーネス１０は、芯線２２と前記芯線２２を覆う絶縁被覆２６とを含む電線２０と、樹脂製の主面３３上に前記電線２０が配設されており、前記主面３３において前記電線２０と接触する部分が前記電線２０の前記絶縁被覆３０と溶着されて電線固定部３４に形成されているシート材３０と、を備える。前記シート材３０のうち前記電線固定部３４における最も大きい厚み寸法Ｂが、前記シート材３０のうち前記電線２０が未配設の部分における厚み寸法Ｃ、Ｄよりも大寸に形成されている。【選択図】図２
