A probe (2) is a three-layer substrate having two faces on which paired electrodes (E1, E2) are formed at corresponding positions and guard patterns (Ge) are formed around the electrodes. The guard patterns and all electrodes are driven by a common probe signal (Vp) to an equal potential, thereby commonly guarding the electrodes. Based on a clamp current of each electrode, a capacitance is found to obtain gap data.
