1. A mobile communication terminal comprising:
- a first unit with a first circuit;
a second unit with a second circuit;
a hinge unit which couples said first unit and said second unit in such a manner that they can rotate and which has a cylindrical axis member whose side face has an openings that leads to the inside of said first unit and to the inside of said second unit; and
a flexible substrate which connects the first circuit and the second circuit and which has such a structure as connects a first belt-like part and a second belt-like part by a middle part so as to form a crank shape, either the first belt-like part or the second belt-like part being rolled with the middle part as an axis to form a roll buffer part, the roll buffer part being housed in the cylindrical axis member of said hinge unit, and a tips of the first and second belt-like parts being pulled into said first and second units through the opening in the cylindrical axis member and connected to the first and second circuits.

Abstract
A folding electronic apparatus invention comprises a flexible substrate where a first belt-like part and a second belt-like part are connected by a middle part so as to form a crank shape. At least one of the first belt-like part and the second belt-like part of the flexible substrate is rolled with the middle part as an axis to form a roll buffer part. The roll buffer part is housed in the hollow of a hinge axis. A tips of the first and second belt-like parts are pulled into a first and second units through an opening in the hinge axis and then connected to the first and second circuits in the first and second units.
