摘要： In a flexible wiring board for use in, for example, a liquid discharge head, wires disposed on a substrate in parallel are covered with a film material. The flexible wiring board is bendable towards one of a front surface side and a back surface side of the substrate and includes a bending line. The bending line is formed by bending the flexible wiring board along a bending direction crossing a longitudinal direction of the wires. The bending line contains the wires. Both ends of the flexible wiring board in the bending direction are located on the bending line. A distance between one of the wires located closest to one end of the flexible wiring board and the one end is larger on the bending line than in another part of the flexible wiring board. Accordingly, even if the flexible wiring board is bent at a small bend radius, peeling does not easily occur between a base film and a cover film.

摘要翻译： 在用于例如液体排出头的柔性布线板中，平行地设置在基板上的布被薄膜材料覆盖。 柔性布线板可以朝向基板的前表面侧和背面侧之一弯曲，并且包括弯曲线。 弯曲线通过沿着与电线的纵向交叉的弯曲方向弯曲柔性布线板而形成。 弯曲线包含电线。 柔性布线板的弯曲方向的两端位于弯曲线上。 位于最靠近柔性线路板的一端的一条电线与一端之间的距离在弯曲线上大于柔性电路板的另一部分。 因此，即使柔性布线板以小的弯曲半径弯曲，也不容易在基膜和覆盖膜之间发生剥离。
