Abstract
A pressure sensor includes a base, a membrane disposed at a distance from the base, a first fixed electrode provided on the base so as to be opposite to the membrane and including a dielectric layer, and a second fixed electrode provided on the base so as to be opposite to the membrane. When pressure that acts on the membrane increases to cause the membrane to sag toward the base, the membrane comes in contact with the dielectric layer of the first fixed electrode before a distance between the membrane and the second fixed electrode becomes constant.
