Abstract
An electronic apparatus which achieves ease of incorporating flexible boards into the electronic apparatus and ease of impedance control at the same time. A first flexible board and a second flexible board are placed along a structure having a bent portion and a flat portion. Differential signal wires are wired on one surface of the first flexible board placed between the structure and the second flexible board, and first ground wires for impedance control of the differential signal wires are wired on the other surface and on a rear side of the differential signal wires. Second ground wires for impedance control of the differential signal wires are wired on one surface of the second flexible board the one surface of the first flexible board faces. A wiring density of the first and second ground wires differs between an area along the bent portion and an area along the flat portion.
