Abstract
A circuit substrate includes a base material, a first electrode, and a second electrode. The base material has an upper side and a lower side opposite to each other in a length direction. The first electrode extends and is configured on the base material along the length direction. The second electrode is configured beside the first electrode and includes a first portion and a second portion connected to each other. The first portion is configured on the base material along the length direction. The second portion is configured on the base material along a width direction and is located between the upper side and the first electrode. A cross-sectional width of the first portion becomes larger from the lower side to the upper side.
