Multilayer substrate
摘要:
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.
