To provide a sensor unit that simultaneously displays other information together with a threshold and a physical quantity. A sensor unit causes a dot-matrix display unit to display a threshold and a physical quantity in a first display form and causes the dot-matrix display unit to display, together with the physical quantity and the threshold, additional information (e.g., a power mode) different from the physical quantity and different from the threshold in a second display form. The area of a third display region 303 for the threshold in the second display form is smaller than the area of a second display region 302 for the threshold in the first display form. The area of a fourth display region 304 for the information in the second display form is obtained by reducing the area of the second display region 302.

A capacitive touch sensor detects proximity of touch presence. The capacitive touch sensor includes a conductive surface at an edge of a substrate thereof.
