<p>PROBLEM TO BE SOLVED: To reduce noise and the resistance or inductance of wiring being connected with a chip capacitor. SOLUTION: The wiring board 1 comprises a chip capacitor 10 contained in a recess 4 on the first major surface 2a of a core board 2, a first multiplayer wiring part 20 formed on the first major surface 2a, a terminal 28 to be connected with an IC chip 29 formed on the upper surface thereof, wiring 26, 27 to be connected with the IC connection terminal 28 provided at the wiring part 20, a second multiplayer wiring part 30 formed on the second major surface 2b of the board 2, an external connection terminal 38 formed on the upper surface thereof, and wiring 36, 37 to be connected with the external connection terminal 38 provided at the wiring part 30 and on the bottom face 4b of the recess 4. The capacitor 10 has a first terminal electrode 12 being connected with the first IC connection wiring 26 on the first major surface 2a side and with the first external connection wiring 36 on the second major surface 2b side, and a second terminal electrode 14 being connected with the second IC connection wiring 27 on the first major surface 2a side and with the second external connection wiring 37 on the second major surface 2b side.</p> |
