Abstract
According to the invention, information processing equipment using a flexible printed-circuit board which does not lose bendability with repeated opening and closing of a display unit, and which suppresses radiation noise from signal wiring is provided. In the configuration of the invention, a first cover film is formed to cover a wiring layer on a first surface of a base film, and a second cover film is formed to cover a wiring layer on a second surface of the base film. Portions of the second cover film and the underlying wiring layer on the second surface in the loop formation region are discontinuously removed in the inward-bending area of the loop, and the base film is exposed in the removed parts. The wiring layer underneath the remaining second cover film, which is not removed, and the wiring layer on the first surface of the base film are electrically connected via through holes penetrating the base film.
