Abstract
In order to keep impedance characteristics to desired values across the entire operating frequency band, an electronic circuit of the present invention includes an integrated circuit, a decoupling capacitor, and a multilayer circuit board on which the integrated circuit and the decoupling capacitor are mounted. In the electronic circuit, a planar land is formed on one or both of a power layer and a ground layer of the multilayer circuit board, the land having densely disposed therein a plurality of via holes that connect a terminal of the integrated circuit and a corresponding terminal of the decoupling capacitor, and the land formed on the power layer or the ground layer is discontinuously disposed at a predetermined interval with a gap having a predetermined width provided therebetween.
