Abstract
A built-in-circuit substrate includes a substrate body, an electrical circuit including inner electrodes provided inside the substrate body and to which an RF signal is input, outer electrodes which are provided on the substrate body so as to be connected to the electrical circuit and which each include an underlying metal layer and a nickel layer covering at least a portion of the underlying metal layer, and a permanent magnet which is arranged on the substrate body. Thus, noise caused by intermodulation distortion generated in the nickel layers of the outer electrodes is prevented.
