Patent ID: 7834441

Claim:
A multilayer substrate comprising: an insulating base member including a plurality of conductive patterns and a plurality of resin films, wherein the resin films are made of a thermoplastic resin and stacked and attached to each other in a stacking direction; an electric element embedded in the insulating base member and including an electrode electrically coupled with at least one of the conductive patterns; and a spacer, wherein: at least one resin film has a through hole in which the electric element is inserted; the one resin film has a plurality of protruding members, each of which protrudes from a surrounding portion of the through hole into the through hole; one protruding member opposes to another one protruding member so that the one and the another one contact and sandwich the electric element; and the spacer is disposed between the one resin film and an adjacent resin film in the stacking direction; the spacer is disposed at a base portion of one of the protruding members; and the spacer is disposed in a direction perpendicular to the stacking direction with respect to the electric element.
