| 摘要 |
A wiring board with built-in capacitors includes a core substrate, and a high dielectric sheet including a lower electrode layer, an upper electrode layer and a dielectric layer, the dielectric layer made of a sintered ceramic body and sandwiched between the lower electrode layer and the upper electrode layer, the lower electrode layer and/or the upper electrode layer being partitioned into multiple electrodes such that the high dielectric sheet has multiple capacitors. The lower electrode layer and/or the upper electrode layer is connected to a ground line and the other one of the lower electrode layer and the upper electrode layer is connected to a power line such that the capacitors are electrically connected in parallel. |
