Patent ID: 7345244

Claim:
A flexible substrate connectable to electrodes provided on an external member, said flexible substrate comprising: a base material having flexibility and including an insulative base film and a conductive film; a plurality of lead parts arranged at an end of the base material, each lead part having a first surface and an opposing second surface and having an end surface extending between the first and second opposing surfaces; and slits formed between and separating the lead parts; wherein each of the lead parts are cantilevered from the base material such that each lead part has a free end away from the base material, the lead parts having a conductive film integrally formed over the first and second opposing surfaces of the lead parts, the conductive film also being formed on at least one of a first surface and a second surface of the flexible substrate, the first surface of the lead part facing the external member; a solder film formed over the conductive film on the first and second surfaces of the lead part and enclosing the end surface of the lead part; and wherein a non-solder adhesive member for temporarily fixing the base material to the external member is provided at a portion of the base material, which portion faces the external member.
