Abstract
A pressure sensor including a first conductor located in a pressure sensing region including a first sensing region and a second sensing region; and a second conductor spaced apart from the first conductor, the second conductor forming capacitance with the first conductor. The first conductor includes a first conductive part located in the first sensing region and a second conductive part located in the second sensing region. The area ratio of the second conductive part with respect to the second sensing region is different from the area ratio of the first conductive part with respect to the first sensing region.
