<p>A printed circuit board (1) comprises a board (11), a plurality of first interconnects (12) provided on the front surface of the board (11), and a plurality of second interconnects (13) provided on the back surface of the board (11). Connection parts (14) are provided between portions of the first interconnects (12) and portions of the second interconnects (13) and do not stick out from the inside of the region where the portions of the first interconnects (12) overlap the portions of the second interconnects (13). The connection parts (14) are disposed so that, when seen from a plan view from the board front surface side, the connection parts (14) extend across the space between a pair of sides, running along the interconnect extension direction, of each first interconnect (12), and extend across the space between a pair of sides, running along the interconnect extension direction, of each second interconnect (13).</p> |
