Abstract
This pinching detection device of a power window is provided with: a sensor electrode provided in a windowpane; a position-detecting electrode that opposes the sensor electrode; and a control unit. The size of an opposing surface area between the sensor electrode and the position-detecting electrode increases as the windowpane is raised. The control unit detects pinching of foreign matter on the basis of a change in capacitance in the sensor electrode and detects a position in the windowpane on the basis of the change in capacitance.
