    • A flat cable that easily bends in a width direction and a production method for the flat cable are provided. A flat cable (FC) includes a plurality of conductors (10) extending in an axial direction, and an insulating sheath (20) that covers these conductors (10) in a state where the conductors (10) are lined up in the width direction. The insulating sheath (20) has an expansion portion (24). The expansion portion (24) expands in a thickness direction orthogonal to the axial direction and the width direction so as to separate from an outer circumferential face of each conductor (10) towards the outside, and thus an internal space permitting relative displacement between the conductors (10) is formed. This flat cable (FC) can be produced by arranging a die, having an inner face including a portion having a shape that expands to the outside in a radial direction, around the circumference of a flat cable material, and forming the expansion portion (24) having a shape following the inner face of the die by heating the insulating sheath (20) within the die and conferring a pressure difference between the inside and outside of the insulating sheath (20).
    • 提供一种容易在宽度方向上弯曲的扁平电缆和扁平电缆的制造方法。 扁平电缆(FC)包括沿轴向延伸的多个导体(10)以及在导体(10)在宽度方向上排列的状态下覆盖这些导体(10)的绝缘护套(20) 。 绝缘套(20)具有一个扩展部分(24)。 扩展部(24)在与轴向和宽度方向正交的厚度方向上扩展,以便从每个导体(10)的外圆周面向外侧分离,因此允许导体之间的相对位移的内部空间 (10)形成。 该扁平电缆(FC)能够通过在扁平电缆材料的周围配置具有包括具有向径向外侧扩展的形状的部分的内表面的模具,并且形成扩张部(24 )通过在模具内加热绝缘护套(20)并赋予绝缘护套(20)的内部和外部之间的压力差而具有跟随模具内表面的形状。
