PROBLEM TO BE SOLVED: To provide an inspection device and a test method for circuit board which can precisely judge quality in continuity/insulation performance of a circuit within the inspecting circuit board even if the circuit board has no inside layer conductive plane, in order to promote efficiency of circuit board inspection process. SOLUTION: This circuit board inspection device is provided with a transmitter (2) emitting electromagnetic wave signal to the inspecting circuit board (3) via a transmission antenna (1), a receiver (6) including a means using one circuit (4) within the inspecting circuit board as a receiving antenna to detect any signal induced into the circuit through electromagnetic induction of the electromagnetic wave signal, and a means (8) comparing the detected signal data with the data for nondefective circuit board to judge whether the circuit within the inspecting circuit board is good or bad in quality.
