    Abstract: A flexible printed circuit board (FPC) is provided, which includes a dielectric layer (110). Copper foil layers (120) and cover layers (160) are sequentially provided from inside to outside on both sides of the dielectric layer (110). The cover layer (160) on one side of the dielectric layer (110) is provided with a reinforced plate (180). The FPC includes a bending area. The copper foil layer (120) and the cover layer (160) on one side at the bending area and the reinforced plate (180) are each provided with a windowed area 190. Edges of the copper foil layer (120), the cover layer (160), and the reinforced plate (180) that are defined by windowed areas (190) are not in one vertical plane. In the structure, stress concentrations in the bending area are distributed, so that the tearing risk to the edges of the bending area is reduced, and the bending resistance of the flexible circuit board is enhanced.

    Abstract: A circuit board to be mounted on a printed circuit board and a mother laminated body are provided, the circuit board being capable of suppressing detachment thereof from the printed circuit board even if the printed circuit board is deformed. A laminated body (11) is configured by induing insulation layers (16) composed of a flexible material that are stacked on one another. External electrodes are provided on a bottom surface of the laminated body (11). Ground conductors (18a, 18b) are provided in the laminated body (11) and harder than the insulation layers (16). The laminated body (11) includes a flexible region (E2) and a rigid region (E1) that is adjacent to the flexible region (E2) when viewed in a plan from a z-axis direction, The rigid region (E1) is defined by the ground conductors (18a, 18b) when viewed in a plan from the z-axis direction, The external electrodes are provided within the flexible region (E2) when viewed in a plan from the z-axis direction.
