Abstract
A flexible flat optical cable includes two flexible base sheets, one or more optical fiber core wires arranged between the base sheets and each comprising at least an optical fiber, and an adhesive layer provided between the base sheets to bond the base sheets. A non-adhesive region is formed on a surface of the base sheets or the adhesive layer adjacent, in a thickness direction of the base sheets, to at least a portion of the optical fiber core wires for allowing a portion of the optical fiber core wires to move in a direction intersecting with an axial direction of the optical fiber core wires.
