Patent ID: 8345437

Claim:
A connection structure for connecting a wiring board to a to-be-connected body having electric contacts, the wiring board including: a flexible base formed of electrically insulating resin and having board-side contacts which are provided on a facing surface of the flexible base that is to face the to-be-connected body; and a cover film which covers the facing surface of the flexible base except the board-side contacts and a non-covered partial region of the facing surface, wherein the connection structure comprises: conduction portions which are formed of electrically conductive resin including a metal material and thermosetting resin and each of which bonds a corresponding one of the electric contacts of the to-be-connected body and a corresponding one of the board-side contacts of the wiring board to each other so as to permit electrical conduction therebetween; and a reinforcement portion formed of the same electrically conductive resin as the conduction portions and disposed at a position which is different from positions of the conductive portions and at which the reinforcement portion extends across both of a surface of the cover film and a surface of the non-covered partial region of the flexible base, the reinforcement portion bonding the to-be-connected body and the wiring board to each other for reinforcing connection therebetween.
