Abstract
A resistance substrate contains a substrate and a resistance part that is formed on an upper surface of the substrate by printing. The resistance part is formed into an arc shape (a C shape) so that a width of the resistance part continually changes. The resistance part is formed so that a part having a narrow width becomes thick and a part having a narrow width becomes thin.
