Combined optical and electrical flexible wiring and production method therefor

A combined optical and electrical flexible wiring producing method, comprising:

• preparing a flexible flat cable with a plurality of conductors aligned parallel on a surface of a first film substrate;
• aligning an optical fiber parallel to the plural conductors on the surface of the first film substrate;
• covering the optical fiber and the plural conductors with a second film substrate in such a manner that a portion of the optical fiber and respective portions of the plural conductors are exposed in a predetermined range;
• forming a light inlet or outlet surface in the exposed portion of the optical fiber;
• forming a resin mount to cover the exposed portions of the plural conductors and the exposed portion of the optical fiber, and forming a light inlet or outlet groove in that resin mount;
• forming one surface of the light inlet or outlet groove into a minor surface to bend an optical axis of the optical fiber;
• forming a wiring pattern on a surface of the resin mount;
• mounting an optical-electrical conversion component for conducting an interconversion between an optical signal and an electrical signal, on the surface of the resin mount and across the light inlet or outlet groove in such a manner that the optical-electrical conversion component faces the mirror surface;
• and
• electrically connecting the optical-electrical conversion component and the conductors via the wiring pattern.
