Flexible flat cable and manufacturing method therefor

A flexible flat cable comprising:

• a reflective member having characteristics close to a light reflectivity of 100% and having a plate shape;
• a pair of light-transmitting signal transmission members disposed on a first surface of the reflective member and spaced apart from each other;
• a pair of conductive signal transmission members disposed on the first surface of the reflective member and spaced apart from each other;
• a reflective adhesive member having characteristics close to a light reflectivity of 100%, fixing the pair of light-transmitting signal transmission members and the pair of conductive signal transmission members to the reflective member, and coupling the reflective member and a non-conductive member;
• the non-conductive member including a first surface contacting the reflective adhesive member, and a second surface opposite to the first surface of the non-conductive member;
• an adhesive member disposed on the second surface of the non-conductive member;
• and
• an electrical shielding member coupled to the non-conductive member through the adhesive member,
• wherein each of the light-transmitting signal transmission member is plate-shaped,
• wherein the reflective adhesive member surrounds each of the light-transmitting signal transmission members and the conductive signal transmission members other than bottom surfaces of the light-transmitting signal transmission members and the conductive signal transmission members, and
• wherein the bottom surfaces face the first surface of the reflective member.
