[EN]The invention relates to a sensor device for measuring resistivity using the four-point method. The inventive device comprises a base element (1) and four electrodes (2) which extend out from one edge (11) of the base such as to overhang same, as well as an insulating structure consisting of at least one insulating layer (5, 6) which is located close to the contact ends (4) of the electrodes (2). The electrodes (2) are connected to the insulating layer (5, 6) such that the insulating structure maintains a fixed distance between the electrodes (2) except in one section (b) close to the contact ends such that the electrodes are flexible and adapt to the sample. The invention also relates to a method of producing the sensor device and to a piece of resistivity measuring equipment.
