Flexible wiring board and light control unit

A flexible wiring board comprising:

• an insulating layer having a support surface extending in a first direction;
• a first sheet adhesive terminal positioned on the support surface;
• a second sheet adhesive terminal positioned on the support surface;
• and
• a weakened part formed on a straight fold line extending in the first direction and configured to induce the flexible wiring board to fold along the straight fold line, wherein
• the first sheet adhesive terminal is spaced from the second sheet adhesive terminal in the first direction and is positioned on a side of the straight fold line opposite to a side on which the second sheet adhesive terminal is positioned, and
• the insulating layer includes a first support piece that supports the first sheet adhesive terminal and is extending in the first direction, and a second support piece that supports the second sheet adhesive terminal and is extending in the first direction, a part of the first support piece that connects to the second support piece is a tip end part of the first support piece in the first direction, a part of the second support piece that connects to the first support piece is a base end part of the second support piece in the first direction, and the flexible wiring board includes the weakened part on a boundary between the tip end part and the base end part.

A light control unit, comprising:

• a light control sheet having an edge part extending in a first direction;
• and
• a flexible wiring board bonded to the edge part of the light control sheet,
• wherein the light control sheet includes a first transparent electrode layer having a first transparent electrode terminal on a first electrode surface, a second transparent electrode layer having a second transparent electrode terminal on a second electrode surface, and a light control layer positioned between the first and second electrode surfaces such that the first and second transparent electrode terminals are exposed from the light control layer, the first and second transparent electrode terminals constitute the edge part and are positioned in the first direction, the flexible wiring board includes an insulating layer including a support surface extending in the first direction, a first sheet adhesive terminal bonded to the first transparent electrode terminal, positioned on the support surface and extending in the first direction, and a second sheet adhesive terminal bonded to the second transparent electrode terminal, positioned on the support surface and extending in the first direction, the support surface is folded along a straight fold line extending in the first direction, and the first sheet adhesive terminal has a shape obtained by translating a shape of the second sheet adhesive terminal along the straight fold line.
