Abstract:
This electronic device is provided with a first circuit board (1), a second circuit board (2), and an interposer board (3). The interposer board (3) has a first main surface (MS1) facing the first circuit board (1), and a second main surface (MS2) facing the second circuit board (2). A first input and output pad and first auxiliary pads are formed on the first main surface (MS1) of the interposer board (3), and a second input and output pad (P2) and second auxiliary pad parts (Pa21, Pa22) are formed on the second main surface (MS2). Lands, to which the first input and output pad and the first auxiliary pads are connected, are formed on the first circuit board (1), and lands, to which the second input and output pad (P2) and the second auxiliary pad parts (Pa21, Pa22) are connected, are formed on the second circuit board (2).
