Abstract
An electrical characteristic measuring substrate includes a plurality of laminated dielectric layers, front-surface coplanar lines disposed at a front surface of the substrate, back-surface coplanar electrodes disposed at a back surface thereof, and interlayer ground electrodes disposed between dielectric layers. First ends of the front-surface coplanar lines define a front-surface component mounting electrode, and first ends of the back-surface coplanar lines define a back-surface component mounting electrode. The front-surface component mounting electrode and the back-surface component mounting electrode have substantially the same pattern when viewed from the direction perpendicular to the front surface. Each of the front-surface component mounting electrode and the back-surface component mounting electrode has an electrode pattern asymmetric about a substantially central line of the front surface or about that of the back surface.
