A wiring board includes a substrate core and a ceramic chip to be embedded therein. The substrate core has a housing opening portion opening at a core main surface. The ceramic chip is accommodated in the housing opening portion so that the core main surface and a chip first main surface face the same way. The ceramic chip includes a plurality of second terminal electrodes comprised of a metallized layer and formed on the chip second main surface so as to protrude therefrom. A projecting portion, disposed on the second main surface side so as to surround a plurality of the second terminal electrodes, is formed on the chip second main surface so as to protrude therefrom.
