MULTILAYER SUBSTRATE
First Claim
1. A multilayer substrate comprising:
- a main body including a plurality of insulating sheets to be stacked and made of a flexible material;
a signal wire disposed in the main body;
a first ground conductor that is provided at one side of the signal wire in a stacking direction in the main body, such that the first ground conductor overlaps the signal wire in a plan view seen from the stacking direction; and
a second ground conductor that is provided at the other side of the signal wire in the stacking direction in the main body, such that the second ground conductor overlaps the signal wire in a plan view seen from the stacking direction;
whereinthe main body including the signal wire retains a curved state by plastic deformation of the first and second ground conductors.

Abstract
A multilayer substrate that retains a curved state without causing fluctuations in electrical characteristics includes a main body including a plurality of insulating sheets to be stacked and made of a flexible material. A signal wire extends in the main body. A ground conductor is provided at a positive-direction side in a z-axis direction relative to the signal wire in the main body, and overlaps the signal line in a plan view seen from the z-axis direction. A ground conductor is provided on a negative-direction side in the z-axis direction relative to the signal wire in the main body, and overlaps the signal line in a plan view seen from the z-axis direction. The state in which the main body is curved so that the signal wire defines an arc is retained by plastic deformation of the ground conductors.
