Abstract:
1. A printed circuit board, comprising: a printed wiring board comprising: a semiconductor package mounted on the surface layer of the printed wiring board, the semiconductor package comprising: wherein, when a region of the surface layer opposed to the main body part is defined as a first region and a region of the surface layer other than the first region is defined as a second region: the first power supply pattern extending from the first main power supply pattern is led from the second region to the first region and is wired to connect the first power supply terminals and the second power supply terminals of the multiple terminal groups; the second power supply pattern extending from the second main power supply pattern is led from the second region to the first region and is wired in a single stroke manner so as to connect the third power supply terminals and the fourth power supply terminals of the multiple terminal groups in this order; the third power supply terminal and the fourth power supply terminal in the same terminal group are connected to each other in the second region; the third power supply terminal of one of two different terminal groups among the multiple terminal groups and the fourth power supply terminal of another one of the two different terminal groups are connected to each other in the first region; and the second power supply pattern is disposed on an outer perimeter side of the semiconductor package with respect to the first power supply pattern when viewed from a center of the semiconductor package.
