Abstract

An electrostatic capacitance detection device including an electrostatic capacitance detection element arranged in a matrix form; a row line arranged in each row for selecting a relevant electrostatic capacitance detection element arranged in a relevant row; an output line arranged in each column for outputting a signal from a relevant electrostatic capacitance detection element arranged in a relevant column, wherein each electrostatic capacitance detection element is provided with a row selection element that controls the outputting of the signal of the relevant electrostatic capacitance detection element to the relevant output line based on the signal from the relevant row, and the signal from the relevant electrostatic capacitance detection element, which is caused to be in a selection state based on the signal from the relevant row line, is outputted to the output line arranged in the relevant electrostatic capacitance detection element.
