Patent ID: 8839513

Claim:
A method of manufacturing a concave connector substrate comprising: preparing a guide substrate having a guide/holding region that guides a plate-shaped connector provided with an electronic device to be connected to a connection position and holds the plate-shaped connector at the connection position and a cut portion for removing a section having a shape corresponding to the guide/holding region; arranging and aligning two wiring substrates, each having wiring lines obtained by integrating connector terminals with cables, a metal layer that is provided on one surface opposite to a surface having the wiring lines formed thereon, and a window that is provided in a region of the metal layer facing the connector terminals, with both surfaces of the guide substrate such that the surface having the wiring lines formed thereon faces the guide substrate, and applying an adhesive to a region of the guide substrate other than the inside of the cut portion to bond the wiring substrates to the guide substrate; pressing a base surface of at least one wiring substrate of the two wiring substrates exposed from the window to bend the wiring substrate and bringing the wiring lines disposed in the bent portion into pressure contact with the inside of the cut portion; and removing the section inside the cut portion to form the guide/holding region, wherein a thickness of the section of the guide substrate is set to be less than a maximum thickness of the plate-shaped connector.
