PROBLEM TO BE SOLVED: To reduce signal loss in signal current wiring, in a wiring structure where the signal current wiring and return current wiring are mounted overlapped in a box body. SOLUTION: The signal current wiring 10a, 10b carry signal current from a first circuit block 100 to a second circuit block 200. The return current wiring 20a carries return current from the second circuit block 200 to the first circuit block 100. The signal current wiring 10a, 10b and the return current wiring 20a are overlapped, staggered from each other in a width direction so as to form a region where the signal-current wiring 10a, 10b and a second wiring-side surface of the box body 300 face each other, without the intervention of the return current wiring 20a, between the second wiring side surface of the box body 300 and the signal current wiring 10a, 10b.
