<p>PURPOSE: To improve the stability of detecting characteristics and the controllability of sensitivity with regard to a pressure detector for detecting the pressure, which is applied from the outside. CONSTITUTION: When an upper substrate 2, wherein a first conductor film 24 is formed on approximately quadrangular pyramid shaped protruding parts 23, is pushed to a lower substrate 25, wherein a second conductor film 26 is formed, the protruding parts 23 are penetrated into the lower substrate 25, and the contact areas of the first and second conductor films 24 and 26 are changed. A pressure detecting means 27 detects the pressure based on the change in contact areas in this constitution.</p> |
