Abstract:
1. A flexible printed board comprising: a base material; a plurality of first conductive pads arranged along an imaginary line on a surface of the base material, the first conductive pads respectively extending with a first width from front end of the first conductive pads to rear ends of the first conductive pads on a front side of the imaginary line; a plurality of second conductive pads arranged along the imaginary line on the surface of the base material, the second conductive pads respectively extending with a second width from front end of the second conductive pads on a rear side of the imaginary line to rear ends of the second conductive pads; first wiring patterns provided between the second conductive pads and extending with a third width from front ends of the first wiring patterns connected to the rear ends of the corresponding first conductive pads, the third width being smaller than the first width and the second width; and a reinforcing layer for reinforcing a reinforcing area extending over the first conductive pads and the first wiring patterns, the reinforcing layer having a front edge defined on a front side of rear ends of the first conductive pads and a rear edge defined on a rear side of the rear ends of the second conductive pads.
