1. A method of manufacturing a pressure sensitive conductive sheet comprising the steps of:

  • applying a magnetic field to a transparent elastic member with a plurality of ferromagnetic conductive particles dispersed therein in a perpendicular direction to a surface of the elastic member for causing the plurality of conductive particles to be joined together to thereby form a linear aggregate;

    curing the elastic member; and

    swelling the elastic member with use of a swelling liquid such that the linear aggregate is segmented into a plurality of conductive elements with predetermined gaps formed therebetween.
