Claim 9:
10. The substrate according to claim 9,
wherein:
the third dielectric substrate includes a plurality of fifth conductive vias, the plurality of fifth conductive vias penetrating the third dielectric substrate from the fifth face to the sixth face and being electrically connected to the first planar conductor,
the fourth dielectric substrate includes a plurality of sixth conductive vias, the plurality of sixth conductive vias penetrating the fourth dielectric substrate from a seventh face to an eighth face and being electrically connected to the third planar conductor,
at least one of the plurality of fifth conductive vias and at least one of the plurality of sixth conductive vias at least partially overlap in the first direction, and
a gap between adjacent fifth conductive vias of the plurality of fifth conductive vias or between adjacent sixth conductive vias of the plurality of sixth conductive vias is less than or equal to half a guide wavelength of a high-frequency signal.
