Flexible substrate and opening/closing electronic device

Abstract

A flexible substrate (200) includes a recessed portion formed on a right edge portion of a first linear portion (210) continuously extending backward from a left end portion of an intermediate linear portion (230). In the case of inserting the flexible substrate (200) for example through a hollow hinge portion (101) openably and closably connecting a first and a second device body (110), (120) of an opening/closing type electronic device (100), upon inserting the first linear portion (210) through the first opening (112) of the first cylindrical hinge portion (118), constituting a part of the hollow hinge portion (101), the recessed portion of the first linear portion (210) is located so as to oppose a right end inner surface of the first opening (112), with a gap therebetween. Accordingly, although the intermediate linear portion (230) is twisted by the opening or closing action of the opening/closing type electronic device (100), disconnection due to interference of the first linear portion (210) with the right end inner surface of the first opening (112) can be prevented. Therefore, the flexible substrate can prevent the trouble of the opening/closing type electronic device, without the need to largely modify the design of an essential component.
