Abstract
A pressure sensor including: a first conductor; a second conductor spaced apart from the first conductor, and positioned so as to form a capacitance with the first conductor; and an elastic member positioned between the first conductor and the second conductor, in which the capacitance varies according to a pressure applied to one or more of the first conductor and the second conductor, and the first conductor has a shape different from that of the second conductor.
