Claim 10:
11. A signal transmission method for performing a process of transmitting a differential signal by use of a flexible printed circuit board,
wherein at least one of connector connection parts of the flexible printed circuit board has a first connection part column and a second connection part column obtained by arranging a plurality of signal line connection parts, the signal line connection parts being connection parts between the signal transmission paths and intra-connector wiring as two column lines in parallel with each other,
the signal transmission method comprising:
transmitting an output from the intra-connector wiring to the signal line connection parts configured in the first connection part column and in the second connection part column; and
transmitting the differential signal over the signal transmission path formed on a back side of the flexible printed circuit board and by way of a VIA (through-hole) formed between the first connection part column and the second connection part column.
