A contact-type electric capacitive displacement sensor includes a stationary element having a stationary plate, a stationary conductive pattern formed on the stationary plate and an insulation film coated on the stationary plate and a displaceable element having a displaceable plate, a displaceable conductive pattern formed on the displaceable plate and an insulation film coated on the displaceable plate. The stationary and the displaceable conductive patterns have a cyclic pattern of conductor to thereby produce a variation of capacitance therebetween when moving relative to each other.
