Claim Text:
1. An electric tactile sense presentation device comprising: an electrode substrate with a contact surface adapted to be worn so as to be in contact with a skin; and a multitude of electrodes formed on the contact surface of said electrode substrate for contact with the skin to present a tactile sense by means of electrical stimulation; wherein said electrode substrate is composed of a flexible circuit body which is flexible to enable a portion thereof in contact with a real object to flexibly deform so as to conform to deformation of the skin, whereby it is configured such that the electrical stimulation by said electrodes is superimposed on the tactile sense of a human being, while maintaining the human tactile sense, wherein said electrode substrate is flexible and has a slit formed therein to promote deformation thereof, and wherein said electrodes are disposed on the contact surface of said electrode substrate such that in a plan view, four electrodes are located at four vertexes of a rhombus shape formed by two pair of equilateral triangles respectively disposed in reverse relation to each other so as to form a unit pattern of said electrodes, and said slit is formed in said electrode substrate along an axis direction between electrodes at opposed vertexes of one of the two pair of equilateral triangles in the rhombus shape of the unit pattern of said electrodes.
