Chip capacitors 20 are provided in a printed circuit board 10 . In this manner, the distance between an IC chip 90 and each chip capacitor 20 is shortened, and the loop inductance is reduced. In addition, the chip capacitors 20 are accommodated in a core substrate 30 having a large thickness. Therefore, the thickness of the printed circuit board does not become large.
