The invention relates to a non-contact type current / voltage converter comprising a composite magnetoelectric material (1), a bias magnet (3), a shielding casing (4), a grounding electrode (5), an voltage input / output electrode (6) and belonging to electric device field, in which, the composite magnetoelectric material is of layer-shaped sandwich structure composed of magnetostrictive material-piezoelectric material-magnetostrictive material; the bias magnet using one block of the magnet for providing the bias magnetic field on one end or two blocks of magnets distributed left and right symmetrically for providing the even bias magnetic field; the shielding casing enwraps the composite magnetoelectric material; the shielding casing is connected with the total ground wire. The device realizes bilateral conversion among voltage-magnetic field strength-current by magnetoelectric, reverse magnetoelectric effects and Faraday electromagnetic induction effect. Compared with the traditional current / voltage converter based on electric circuit, the device has advantages of passive, bidirectional reversibility, inactive mode, fast response speed, safety, isolation, simple design, low cost and good compatibility with other devices.
