ABSTRACT:
A capacitance type sensor includes a substrate, a group of electrodes fixed on an upper face of the substrate, a movable electrode plate having an electrode on its lower side and a gap between the group of fixed electrodes on the substrate and the electrode on the movable electrode plate. The gap is formed with a solder layer, a conductive elastomer layer, a conductive paint layer, or a conductive adhesive material layer provided on the substrate. The electrode on the movable electrode plate is made of conductive rubber plate or conductive elastomer plate.
