ELECTRICAL CIRCUIT SYSTEM, ANTENNA SYSTEM AND CIRCUIT SHIELD CASE

摘要

[Problem] To provide an electrical circuit system in which electronic components can be integrated within a predetermined limited region, and in which electronic component mounting surfaces are laminated in the vertical direction and connected with each other. [Solution] An electronic component is mounted on at least one surface of one substrate 10. An electronic component is mounted on at least one surface of another substrate 20. A connection member 30 connects the substrate 10 and the substrate 20 with each other in such a manner that the substrate 10 and the substrate 20 face each other. Electrical circuits are respectively formed in a predetermined region of the substrate 10 and a region of the substrate 20 corresponding to the predetermined region. The connection member 30 electrically connects the electrical circuit formed on the substrate 10 and the electrical circuit formed on the substrate 20 with each other.
