PROBLEM TO BE SOLVED: To provide a mounting board on which an electronic device mounted on an electronic device or an electronic component is mounted, which realizes thinning and has flexibility and resistance to bending. A circuit board 10FD according to the present invention is a mounting board formed by mounting a semiconductor chip 2 having a terminal forming surface 2a on one side of which is provided with a pad 7 on a flexible substrate 1, and the pad 7 includes: It is electrically connected to the metal wiring 4 formed on the flexible substrate 1, and the terminal forming surface 2a of the semiconductor chip 2 is substantially equal to the neutral surface np in the thickness direction of the mounting substrate 10FD. It is arranged. [Selection] Figure 1 |
