ELECTRONIC CIRCUIT AND ITS MANUFACTURING METHOD, AND MOBILE TERMINAL WITH ELECTRONIC CIRCUIT

摘要

PROBLEM TO BE SOLVED: To effectively suppress an electromagnetic wave noise without blocking its light weight and without raising its cost. SOLUTION: A flexible printed wiring board 1 includes a ground layer 4 exposing outside on the back side corresponding to the surface side with an electronic component 2 mounted. A conductor-made reinforced board 10 has an opening 11 and adhered to the backside of the electronic component mounted surface of the flexible printed wiring board 1. A conductor-made cushion material 30 is arranged so as to be sandwiched between the exposed ground layer 4 and conductor-made reinforced board 10 of the flexible wiring board 1 and a ground layer 21 of a main wiring board 20 to ground the exposed ground layer 4 and the conductor-made reincorced board 10 of the flexible printed wiring board 1 to the ground layer 21 of the main wiring board 20.
