Electronic component including multilayer substrate

An electronic component including a multilayer substrate, the multilayer substrate comprising:

• a plurality of dielectric layers stacked on one another;
• a first conductor pattern which is disposed along principal surfaces of the dielectric layers and which is electrically connected to a ground;
• and
• a second conductor pattern which is disposed along the principal surfaces of the dielectric layers and which is opposed to the first conductor pattern only through the dielectric layer therebetween, the second conductor pattern forming an inductor element, a stripline, or a microstrip line, which is electrically connected to an element other than a ground,
• wherein an opening is formed in the first conductor pattern, and only the dielectric layers that sandwich the first conductor pattern therebetween in a stacking direction of the dielectric layers are bonded to each other via the opening, and
• wherein, as viewed from the stacking direction in which the dielectric layers are stacked, the second conductor pattern substantially entirely overlaps portions other than the openings in the first conductor.
