Abstract
A pressure sensor comprising: a base film on which a conductor pattern having one or more electrodes is formed; a cover film laminated on the base film so as to cover the electrodes of the conductor pattern; and a spacer disposed between the cover film and the base film so as to form a hollow portion having a predetermined gap between the electrode and the cover film; wherein a portion corresponding to the hollow portion of the cover film is constructed such that it has a pressure sensing part which is able to deform in a direction to move toward and away from the electrode in accordance with pressure, and of which contact resistance changes in accordance with a contact pressure thereof with the electrode, so that the pressure sensing part detects the pressure by a change of the contact resistance.
