ABSTRACT:
A chip capacitor20is provided in a core substrate30of a printed circuit board10. This makes it possible to shorten a distance between an IC chip90and the chip capacitor20and to reduce loop inductance. Since the core substrate30is constituted by provided a first resin substrate30a, a second resin substrate30band a third resin substrate30cin a multilayer manner, the core substrate30can obtain sufficient strength.
