Abstract The conventional variable resistor has a problem in that, because a pressure-sensitive member made of a pressure-sensitive conductive rubber is used, a serious scattering is caused in the characteristic (change curve), and scattering of thickness in the manufacture of the pressure-sensitive member results in a large scatter of the characteristic (change curve). The variable resistor of the invention uses the first resistor pattern forming the variable resistor. It is therefore possible to provide a variable resistor which scattering in the manufacture is smaller, can achieve a uniform resistance change characteristic, and gives a high accuracy.
