Abstract
In a multilayer substrate, ground electrodes are spaced apart from each other in a thickness direction of a laminate substrate and are adjacent to signal lines in a width direction of the signal lines. In a first transmission line region in which a maximum line width of the signal lines is smallest, the signal lines do not overlap any of the ground electrodes in the thickness direction of the laminate substrate. In a second transmission line region in which the maximum line width of the signal lines is largest, one ground electrode among the ground electrodes overlaps the signal lines other than the signal line adjacent to the one ground electrode among the signal lines.

A multilayer substrate comprising:
- a laminate substrate including a plurality of insulating layers that are laminated;
- an alternating current signal line in the laminate substrate and including a plurality of signal lines spaced apart from each other in a thickness direction of the laminate substrate, the plurality of signal lines being electrically connected by a plurality of connection conductors penetrating one of the plurality of insulating layers in the thickness direction;
- and
- a plurality of ground electrodes in the laminate substrate and being spaced apart from each other in the thickness direction, the plurality of ground electrodes being adjacent to the plurality of signal lines in a width direction of the plurality of signal lines;
- wherein
- in a first transmission line region in which a maximum line width of the plurality of signal lines is smallest, the plurality of signal lines do not overlap any of the plurality of ground electrodes in the thickness direction;
- and
- in a second transmission line region in which the maximum line width of the plurality of signal lines is largest, one ground electrode among the plurality of ground electrodes overlaps a signal line other than a signal line adjacent to the one ground electrode among the plurality of signal lines.
