Eddy current sensor with an exploring coil (2) wound on a coil form (32), with two terminals (6, 7), a source of ac voltage, an electrically conductive measuring probe (3), and an evaluation circuit, wherein the measuring probe (3) is displaceable relative to the exploring coil (2), and the evaluation circuit generates an evaluation signal as a function of the position of the measuring probe (3), wherein the eddy current sensor comprises an electrode (4) with a tap (8) for enabling electrical contact, the electrode forming together with the windings of the exploring coil (2) and an intermediate layer (33) a component with distributed electromagnetic parameters, whose output signals are used to determine the position of the measuring probe (3).
