Electrical connection structure of electronic components

Abstract

[Problem] To provide an electrical connection structure for electronic components that can suppress the increase in signal transmission loss even when the distance between the substrate connector and the electronic component increases. [Solution] A connection structure in which a first optical module (1) mounted on a first circuit board (P1) is electrically connected to an ASIC 3 mounted on a second circuit board (P2), and a second optical module (2) mounted on the second circuit board (P2) is electrically connected to the ASIC 3; the connection structure is as follows: the first circuit board (P1) and the second circuit board (P2) are connected by substrate connectors (4, 5, 6), and at the substrate connectors (4, 5), a first relay substrate for cables is directly connected to a first connector and connected to a target connector (7, 8) located away from the second connector through a flat conductor (F), a second relay substrate for cables is directly connected to the second connector and connected to the target connector (7, 8) through a flat conductor (F), and a relay substrate for connectors is directly connected to both the first connector and the second connector.
