Abstract
An object of the present disclosure is to provide a circuit board capable of achieving improved heat dissipation characteristics. The circuit board includes a substrate having a ceramic board as a base material; and a thin film capacitor mounted on the substrate such that a mounting surface faces the conductor layer. The thin film capacitor includes the dielectric layer, first and second capacitor electrodes, formed on one and the other surfaces of the dielectric layer. The capacitor electrode is connected to the wiring pattern included in the conductor layer. The capacitor electrode or a terminal electrode connected thereto is exposed to the upper surface of the thin film capacitor that faces away from the mounting surface.
