PROBLEM TO BE SOLVED: To provide a printed circuit board which can transmit a high-speed signal at a low cost without deteriorating processability.SOLUTION: A printed circuit board is formed by laminating substrates in each of which glass cloth is included in resin and wiring is provided on at least one surface. In the printed circuit board, at least one of substrates in which wiring for transmitting a higher-speed signal than signals transmitted by the other substrates is provided includes glass cloth having a characteristic different from those of the other substrates. |
