Patent attributes
In a flex-rigid wiring board in which a rigid substrate formed from a rigid base material and a flexible substrate formed from a flexible base material are stack-joined and electrically connected to each other, the flexible substrate including a conductive layer having interconnecting electrode pads provided on at least one surface thereof, and the rigid substrate including a conductive layer having interconnecting electrode pads provided on at least one surface thereof in a position opposite to the interconnecting electrode pads on the rigid substrate, are locally connected electrically to each other with an anisotropic conductive adhesive layer interposed between conductive layers of substrate portions each including at least the interconnecting electrode pads.
