PROBLEM TO BE SOLVED: To reliably inspect a stripe-like electrode pattern connected with one end to a common electrode without being affected by the position precision of the electrode pattern. SOLUTION: In this electrode pattern inspecting method, a constant DC current is applied to one end of a transparent electrode 21a by a constant current applying terminal 2, a voltage is measured from one end of an adjacent transparent electrode 21b by a voltage detecting terminal 4, and a common electrode 22 near the transparent electrodes 21a, 21b is grounded by a brush-like earth terminal 3. When a wire severance occurs on the transparent electrode 21a, a constant DC current applying circuit 5 detects a voltage saturation state. When a short circuit occurs, a DC voltage detecting circuit 6 detects a voltage change. A short circuit/wire severance memory circuit 7 stores the detected voltage change as defect information and detects the wire severance or short circuit based on this defect information.
