Abstract

A multilayer substrate includes a plurality of plates laminated in a thickness direction of the multilayer substrate, a resin layer provided between the plurality of plates adjacent in the thickness direction, an internal conductive layer provided between the plurality of plates adjacent in the thickness direction, and an external conductive layer provided over an outer surface of each plate of the plurality of plates located at both ends in the thickness direction, wherein a total thickness of the internal conductive layer and the external conductive layer is equal to or less than 25% of a total thickness of the plurality of plates.

Claims (15)

1. A multilayer substrate comprising:

a plurality of plates laminated in a thickness direction of the multilayer substrate;

a resin layer provided between the plurality of plates adjacent in the thickness direction;

an internal conductive layer provided between the plurality of plates adjacent in the thickness direction; and

an external conductive layer provided over an outer surface of each plate of the plurality of plates located at both ends in the thickness direction,

wherein a total thickness of the internal conductive layer and the external conductive layer is equal to or less than 25% of a total thickness of the plurality of plates, and

wherein the plate is a glass plate.

2. The multilayer substrate according to claim 1 ,

wherein the total thickness of the internal conductive layer and the external conductive layer is equal to or less than 20% of the total thickness of the plurality of plates.

3. The multilayer substrate according to claim 1 ,

wherein a plate of the plurality of plates has brittle properties, and an elastic modulus of the plate is equal to or less than 80 GPa.

4. The multilayer substrate according to claim 1 ,
