Abstract
A chip type capacitor with a multi-layer structure comprising a plurality of inner electrodes classified into two groups one being used as parts of signal lines and the other being connected to grounded lines. Each of the inner electrodes for radio frequency passages has a pair of inwardly extending recesses adapted to make current flows generated in the inner electrode by radio frequency noise be opposite to each other. Each of at least two grounded inner electrode pairs is interposed between vertically adjacent inner electrodes used as parts of signal lines. The inner electrodes of each pair are connected to ground terminals, respectively, and have a shape formed by removing one protruded grounding portion from a cross shape. With this arrangement, the current flows in the inner electrodes of each pair are opposite to each other, so that electromagnetic fields generated by the current flows through the inner electrodes offset each other, thereby enabling the equivalent serial resistance at radio frequency to be decreased and the inductance to be decreased.
