Claim 11:
12. The substrate according to claim 1,
wherein:
the fourth dielectric substrate includes a seventh conductive via penetrating the fourth dielectric substrate from a seventh face to an eighth face,
the substrate further comprises:
a fifth dielectric substrate including a ninth face, a tenth face, and an eighth conductive via penetrating the fifth dielectric substrate from the ninth face to the tenth face;
a third planar conductor provided between the fourth dielectric substrate and the fifth dielectric substrate, the third planar conductor being located away from the seventh conductive via and the eighth conductive via;
a sixth dielectric substrate including an eleventh face, a twelfth face, and a second through-hole penetrating the sixth dielectric substrate from the eleventh face to the twelfth face; and
a third signal line provided between the fifth dielectric substrate and the sixth dielectric substrate,

at least a part of a second inner wall of the sixth dielectric substrate at a portion where the second through-hole is provided is not covered with a conductor,
the second through-hole and the eighth conductive via at least partially overlap in a second direction in which at least one of the seventh conductive via and the eighth conductive via penetrate,
the seventh conductive via and the eighth conductive via at least partially overlap in the second direction, and
the second conductive via and the seventh conductive via do not overlap in at least one of the first direction and the second direction.
