A substrate having an embedded passive element and its manufacturing method are provided to restrain the warpage of the substrate itself and to prevent the influence of a warped substrate on the passive element. A metal line pattern is formed under a passive element(240) corresponding to an electrode structure of the passive element. The passive element is molded by using a molding material(250). The molded passive element is mounted in a cavity of a substrate. The passive element is one selected from a group consisting of a resistor, an inductor and a condenser. A stack type ceramic condenser is used as the condenser. |
