CIRCUIT BOARD

In a circuit board (700A), a first capacitor (410) extends from a wiring pattern (110) to a region located on one side of the wiring pattern (110) in the width direction. A second capacitor (420) extends from the wiring pattern (110) to a region located on the other side of the wiring pattern (110)...

Zusammenfassung:	In a circuit board (700A), a first capacitor (410) extends from a wiring pattern (110) to a region located on one side of the wiring pattern (110) in the width direction. A second capacitor (420) extends from the wiring pattern (110) to a region located on the other side of the wiring pattern (110) in the width direction. With a semiconductor device (300) mounted on the circuit board (700A), a power supply terminal (320) is electrically connected to the wiring pattern (110). The semiconductor device (300), the wiring pattern (110), the first capacitor (410), a first interlayer joint (510), a ground plane (210), and a third interlayer joint (530) constitute a first closed circuit. The semiconductor device (300), the wiring pattern (110), the second capacitor (420), a second interlayer joint (520), the ground plane (210), and the third interlayer joint (530) constitute a second closed circuit.
